Cookies will only be sent in a first-party context and not be sent along with requests initiated by third party websites. Configuration options for registering a custom scheme. These values are used when calling AddCustomScheme. Register scheme without options set If Standard is set the scheme will be treated as a standard scheme. Standard schemes are subject to URL canonicalization and parsing rules as defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available at http://www.ietf.org/rfc/rfc1738.txt In particular, the syntax for standard scheme URLs must be of the form: 
              [scheme]://[username]:[password]@[host]:[port]/[url-path]
Standard scheme URLs must have a host component that is a fully qualified domain name as defined in Section 3.5 of RFC 1034 [13] and Section 2.1 of RFC 1123. These URLs will be canonicalized to "scheme://host/path" in the simplest case and "scheme://username:password@host:port/path" in the most explicit case. For example, "scheme:host/path" and "scheme:///host/path" will both be canonicalized to "scheme://host/path". The origin of a standard scheme URL is the combination of scheme, host and port (i.e., "scheme://host:port" in the most explicit case). For non-standard scheme URLs only the "scheme:" component is parsed and canonicalized. The remainder of the URL will be passed to the handler as- is. For example, "scheme:///some%20text" will remain the same. Non-standard scheme URLs cannot be used as a target for form submission. If Local is set the scheme will be treated with the same security rules as those applied to "file" URLs. Normal pages cannot link to or access local URLs. Also, by default, local URLs can only perform XMLHttpRequest calls to the same URL (origin + path) that originated the request. To allow XMLHttpRequest calls from a local URL to other URLs with the same origin set the CefSettings.FileAccessFromFileUrlsAllowed value to true. To allow XMLHttpRequest calls from a local URL to all origins set the CefSettings.UniversalAccessFromFileUrlsAllowed value to true. If DisplayIsolated is set the scheme can only be displayed from other content hosted with the same scheme. For example, pages in other origins cannot create iframes or hyperlinks to URLs with the scheme. For schemes that must be accessible from other schemes don't set this, set CorsEnabled, and use CORS "Access-Control-Allow-Origin" headers to further restrict access. If Secure is set the scheme will be treated with the same security rules as those applied to "https" URLs. For example, loading this scheme from other secure schemes will not trigger mixed content warnings. If CorsEnabled is set the scheme can be sent CORS requests. This value should be set in most cases where Standard is set. If CspBypassing is set the scheme can bypass Content-Security-Policy (CSP) checks. This value should not be set in most cases where Standard is set. If FetchEnabled is set the scheme can perform Fetch API requests. Describes how to interpret the alpha component of a pixel.

This class provides default implementations of the methods from , therefore providing a convenience base class for a custom implementation. You need only override the methods you require. IMPORTANT: behaviour of this implementation differs from the default, the WM_CLOSE message is only sent by default for popups (return false), for the main browser we return true to cancel this behaviour. Called when a browser has recieved a request to close. This may result directly from a call to CefBrowserHost::CloseBrowser() or indirectly if the browser is a top-level OS window created by CEF and the user attempts to close the window. This method will be called after the JavaScript 'onunload' event has been fired. It will not be called for browsers after the associated OS window has been destroyed (for those browsers it is no longer possible to cancel the close). If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique. !!IMPORTANT!!: Behaviour of this implementation differs from the default, the WM_CLOSE message is only sent by default for popups (return false), for the main browser we return true to cancel this behaviour. If an application provides its own top-level window it should handle OS close notifications by calling CefBrowserHost::CloseBrowser(false) instead of immediately closing (see the example below). This gives CEF an opportunity to process the 'onbeforeunload' event and optionally cancel the close before DoClose() is called. The CefLifeSpanHandler::OnBeforeClose() method will be called immediately before the browser object is destroyed. The application should only exit after OnBeforeClose() has been called for all existing browsers. If the browser represents a modal window and a custom modal loop implementation was provided in CefLifeSpanHandler::RunModal() this callback should be used to restore the opener window to a usable state. By way of example consider what should happen during window close when the browser is parented to an application-provided top-level OS window. 1. User clicks the window close button which sends an OS close notification (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). 2. Application's top-level window receives the close notification and: A. Calls CefBrowserHost::CloseBrowser(false). B. Cancels the window close. 3. JavaScript 'onbeforeunload' handler executes and shows the close confirmation dialog (which can be overridden via CefJSDialogHandler::OnBeforeUnloadDialog()). 4. User approves the close. 5. JavaScript 'onunload' handler executes. 6. Application's DoClose() handler is called. Application will: A. Set a flag to indicate that the next close attempt will be allowed. B. Return false. 7. CEF sends an OS close notification. 8. Application's top-level window receives the OS close notification and allows the window to close based on the flag from #6B. 9. Browser OS window is destroyed. 10. Application's CefLifeSpanHandler::OnBeforeClose() handler is called and the browser object is destroyed. 11. Application exits by calling CefQuitMessageLoop() if no other browsers exist. the ChromiumWebBrowser control The browser instance - check if IsDisposed as it's possible when the browser is disposing For default behaviour return false Called after a new browser is created. the ChromiumWebBrowser control The browser instance Called before a CefBrowser window (either the main browser for , or one of its children) the ChromiumWebBrowser control The browser instance Called before a popup window is created. the ChromiumWebBrowser control The browser instance that launched this popup.

EXPERIMENTAL - A newly created browser that will host the popup. Set to null for default behaviour. To cancel creation of the popup window return true otherwise return false. CEF documentation: Called on the IO thread before a new popup window is created. The |browser| and |frame| parameters represent the source of the popup request. The |target_url| and |target_frame_name| values may be empty if none were specified with the request. The |popupFeatures| structure contains information about the requested popup window. To allow creation of the popup window optionally modify |windowInfo|, |client|, |settings| and |no_javascript_access| and return false. To cancel creation of the popup window return true. The |client| and |settings| values will default to the source browser's values.

Identifies the for BrowserProcess to RenderProcess communication Gets or sets the name of the managed property. Gets or sets the name of the property in the JavaScript runtime. Params this method expects Number of Params this function exepects The Return type of the method This maps the registered objects in the browser process to the reflection data necessary to update the objects, and mapping information to how the object/method/proprerty will be exposed to JavaScript. Identifies the for BrowserProcess to RenderProcess communication Indicate if this object bound as async Gets the methods of the . Gets the properties of the . A javascript object is created for every object, even those that are sub objects it's important we only transmit the Root Objects (top level/parent) Gets or sets the value. This class manages the registration of objects in the browser process to be exposed to JavaScript in the renderer process. Registration performs method, parameter, property type analysis of the registered objects into meta-data tied to reflection data for later use. This class also is the adaptation layer between the BrowserProcessService and the registered objects. This means when the renderer wants to call an exposed method, get a property of an object, or set a property of an object in the browser process, that this class does deals with the previously created meta-data and invokes the correct behavior via reflection APIs. All of the registered objects are tracked via meta-data for the objects expressed starting with the JavaScriptObject type. A hash from assigned object ids to the objects, this is done to speed up finding the object in O(1) time instead of traversing the JavaScriptRootObject tree. Javascript Name converter Has the browser this repository is associated with been initilized (set in OnAfterCreated) Configurable settings for this repository, such as the property names CefSharp injects into the window.

Javascript Binding Settings The Javascript methods that CefSharp provides in relation to JavaScript Binding are created using a Global (window) Object. Settings this property allows you to disable the creation of this object. Features like EvaluateScriptAsPromiseAsync that rely on the creation of this object will no longer function. The Javascript methods that CefSharp provides in relation to JavaScript Binding are created using a Global (window) Object. Settings this property allows you to customise the name of this object. If not specified then both cefSharp and CefSharp objects will be created e.g. cefSharp.bindObjectAsync, CefSharp.BindObjectAsync. If specified then your custom name will be used, if the name starts with a lowercase letter then all the functions will be lowercase, e.g. myObjName.bindObjectAsync otherwise the functions will start with a uppercase letter e.g. MyObjName.BindObjectAsync This object is also accessible through the window property. e.g. window.cefSharp.bindObjectAsync Objects registered using will be automatically bound when a V8Context is created. (Soon as the Javascript context is created for a browser). This behaviour is like that seen with Javascript Binding in version 57 and earlier. When using an the method is call for all methods (the default is to call InterceptAsync only for methods that return a Task). This only applies when is of type CamelCaseJavascriptNameConverter converts .Net property/method names to camcel case. Get the javascript name for the property/field/method. Typically this would be based on property/field/method javascript name This method exists for backwards compatability reasons, historically only the bound methods/fields/properties were converted. Objects returned from a method call were not translated. To preserve this functionality for upgrading users we split this into two methods.

Typically thie method would return the same result as Issue #2442 property/field/method javascript name Legacy Naming converter. Used by default for backwards compatability Issue #2442 Class used to make a URL request. URL requests are not associated with a browser instance so no CefClient callbacks will be executed. URL requests can be created on any valid CEF thread in either the browser or render process. Once created the methods of the URL request object must be accessed on the same thread that created it. True if the response was served from the cache. The response, or null if no response information is available The request status. Interface that should be implemented by the CefURLRequest client. The methods of this class will be called on the same thread that created the request unless otherwise documented. Called on the CEF IO thread when the browser needs credentials from the user. This method will only be called for requests initiated from the browser process. indicates whether the host is a proxy server. the hostname. the port number. realm scheme is a callback for authentication information Return true to continue the request and call when the authentication information is available. If the request has an associated browser/frame then returning false will result in a call to on the associated with that browser, if any. Otherwise, returning false will cancel the request immediately. Called when some part of the response is read. This method will not be called if the flag is set on the request. request A stream containing the bytes received since the last call. Cannot be used outside the scope of this method. Notifies the client of download progress. request denotes the number of bytes received up to the call is the expected total size of the response (or -1 if not determined). Notifies the client that the request has completed. Use the property to determine if the request was successful or not. request Notifies the client of upload progress. This method will only be called if the UR_FLAG_REPORT_UPLOAD_PROGRESS flag is set on the request. request denotes the number of bytes sent so far. is the total size of uploading data (or -1 if chunked upload is enabled). Legacy ResourceHandler, will be removed when CEF removes the old code path for it's CefResourceHandler implementation. This is the older and well tested variant. It doesn't however support range request headers (seek). Gets or sets the Charset Gets or sets the Mime Type. Gets or sets the resource stream. Gets or sets the http status code. Gets or sets the status text. Gets or sets ResponseLength, when you know the size of your Stream (Response) set this property. This is optional. If you use a MemoryStream and don't provide a value here then it will be cast and it's size used Gets or sets the headers. The headers. When true the Stream will be Disposed when this instance is Disposed. The default value for this property is false. If the ErrorCode is set then the response will be ignored and the errorCode returned. Initializes a new instance of the class. Optional mimeType defaults to Optional Stream - must be set at some point to provide a valid response When true the Stream will be disposed when this instance is Diposed, you will be unable to use this ResourceHandler after the Stream has been disposed response charset Begin processing the request. If you have the data in memory you can execute the callback immediately and return true. For Async processing you would typically spawn a Task to perform processing, then return true. When the processing is complete execute callback.Continue(); In your processing Task, simply set the StatusCode, StatusText, MimeType, ResponseLength and Stream The request object. The callback used to Continue or Cancel the request (async). To handle the request return true and call once the response header information is available can also be called from inside this method if header information is available immediately). To cancel the request return false. Called if the request is cancelled Dispose of resources here Populate the response stream, response length. When this method is called the response should be fully populated with data. It is possible to redirect to another url at this point in time. NOTE: It's no longer manditory to implement this method, you can simply populate the properties of this instance and they will be set by the default implementation. The response object used to set Headers, StatusCode, etc length of the response If set the request will be redirect to specified Url The response stream Provides the capability intercept async/sync Net method calls made from javascript as part of the JavascriptBinding (JSB) implementation. One example use case is logging method calls. Extends to add async support. Called before an async method is invoked. You are now responsible for evaluating the function and returning the result.

If set the cache will be skipped when handling the request. Setting this value is equivalent to specifying the "Cache-Control: no-cache" request header. Setting this value in combination with OnlyFromCache will cause the request to fail. If set the request will fail if it cannot be served from the cache (or some equivalent local store). Setting this value is equivalent to specifying the "Cache-Control: only-if-cached" request header. Setting this value in combination with SkipCache or DisableCache will cause the request to fail. If set the cache will not be used at all. Setting this value is equivalent to specifying the "Cache-Control: no-store" request header. Setting this value in combination with OnlyFromCache will cause the request to fail. If set user name, password, and cookies may be sent with the request, and cookies may be saved from the response. If set upload progress events will be generated when a request has a body. If set the CefURLRequestClient::OnDownloadData method will not be called. If set 5XX redirect errors will be propagated to the observer instead of automatically re-tried. This currently only applies for requests originated in the browser process. If set 3XX responses will cause the fetch to halt immediately rather than continue through the redirect. Implement this interface to receive accessibility notification when accessibility events have been registered. It's important to note that the methods of this interface are called on a CEF UI thread, which by default is not the same as your application UI thread.

The must be writable, no data will be copied otherwise. The StreamResponseFilter will release it's reference (set to null) to the when it's Disposed. StreamResponseFilter constructor a writable stream implementation that uses an OWIN capable host of fulfilling requests. Can be used with NancyFx or AspNet Core TODO: - Multipart post data - Cancellation Token Read the request, then process it through the OWEN pipeline then populate the response properties. request callback always returns true as we'll handle all requests this handler is registered for. implementation that takes an OWIN AppFunc and uses an to fulfill each requests. FolderSchemeHandlerFactory is a very simple scheme handler that allows you to map requests for urls to a folder on your file system. For example creating a setting the rootFolder to c:\projects\CefSharp\CefSharp.Example\Resources registering the scheme handler is being deprecated in favour of using Chromiums native mimeType lookup which is accessible using Cef.GetMimeType, this method is however not directly available as it exists in CefSharp.Core, to get around this we set this static delegate with a reference to Cef.GetMimeType when Cef.Initialize is called. Initialize a new instance of FolderSchemeHandlerFactory Root Folder where all your files exist, requests cannot be made outside of this folder if not null then schemeName checking will be implemented if not null then hostName checking will be implemented default page if no page specified, defaults to index.html file share mode used to open resources, defaults to FileShare.Read If the file requested is within the rootFolder then a IResourceHandler reference to the file requested will be returned otherwise a 404 ResourceHandler will be returned. the browser window that originated the request or null if the request did not originate from a browser window (for example, if the request came from CefURLRequest). frame that originated the request or null if the request did not originate from a browser window (for example, if the request came from CefURLRequest). the scheme name The request.

Lists the errors that can be reported during Widevine Content Decryption Module (CDM) registration. No error. Registration completed successfully. Required files or manifest contents are missing. The CDM is incompatible with the current Chromium version. CDM registration is not supported at this time. This file contains the list of network errors. For a complete up-to-date list, see the CEF source code (cef_errorcode_t in include/internal/cef_types.h) and the Chromium source code (net/base/net_error_list.h). No error occurred. An asynchronous IO operation is not yet complete. This usually does not indicate a fatal error. Typically this error will be generated as a notification to wait for some external notification that the IO operation finally completed. A generic failure occurred. A request was aborted, possibly by the user. An argument to the function is incorrect. The handle or file descriptor is invalid. The file or directory cannot be found. An operation timed out. The file is too large. An unexpected error. This may be caused by a programming mistake or an invalid assumption Permission to access a resource, other than the network, was denied. The operation failed because of unimplemented functionality. There were not enough resources to complete the operation. Memory allocation failed. The file upload failed because the file's modification time was different from the expectation. The socket is not connected. The file already exists. The path or file name is too long. Not enough room left on the disk. The file has a virus. The client chose to block the request. The network changed. The request was blocked by the URL block list configured by the domain administrator. The socket is already connected. The request was blocked because the forced reenrollment check is still pending. This error can only occur on ChromeOS. The error can be emitted by code in chrome/browser/policy/policy_helpers.cc. A connection was closed (corresponding to a TCP FIN). A connection was reset (corresponding to a TCP RST). A connection attempt was refused. A connection timed out as a result of not receiving an ACK for data sent. This can include a FIN packet that did not get ACK'd. A connection attempt failed. The host name could not be resolved. The Internet connection has been lost. An SSL protocol error occurred. The IP address or port number is invalid (e.g., cannot connect to the IP address 0 or the port 0). The IP address is unreachable. This usually means that there is no route to the specified host or network. The server requested a client certificate for SSL client authentication. A tunnel connection through the proxy could not be established. No SSL protocol versions are enabled. The client and server don't support a common SSL protocol version or cipher suite. The server requested a renegotiation (rehandshake). The proxy requested authentication (for tunnel establishment) with an unsupported method. During SSL renegotiation (rehandshake), the server sent a certificate with an error. Note: this error is not in the -2xx range so that it won't be handled as a certificate error. The SSL handshake failed because of a bad or missing client certificate. A connection attempt timed out. There are too many pending DNS resolves, so a request in the queue was aborted. Failed establishing a connection to the SOCKS proxy server for a target host. The SOCKS proxy server failed establishing connection to the target host because that host is unreachable. The request to negotiate an alternate protocol failed. The peer sent an SSL no_renegotiation alert message. Winsock sometimes reports more data written than passed. This is probably due to a broken LSP. An SSL peer sent us a fatal decompression_failure alert. This typically occurs when a peer selects DEFLATE compression in the mistaken belief that it supports it. An SSL peer sent us a fatal bad_record_mac alert. This has been observed from servers with buggy DEFLATE support. The proxy requested authentication (for tunnel establishment). Could not create a connection to the proxy server. An error occurred either in resolving its name, or in connecting a socket to it. Note that this does NOT include failures during the actual "CONNECT" method of an HTTP proxy. A mandatory proxy configuration could not be used. Currently this means that a mandatory PAC script could not be fetched, parsed or executed. We've hit the max socket limit for the socket pool while preconnecting. We don't bother trying to preconnect more sockets. The permission to use the SSL client certificate's private key was denied. The SSL client certificate has no private key. The certificate presented by the HTTPS Proxy was invalid. An error occurred when trying to do a name resolution (DNS). Permission to access the network was denied. This is used to distinguish errors that were most likely caused by a firewall from other access denied errors. See also ERR_ACCESS_DENIED. The request throttler module cancelled this request to avoid DDOS. A request to create an SSL tunnel connection through the HTTPS proxy received a non-200 (OK) and non-407 (Proxy Auth) response. The response body might include a description of why the request failed. We were unable to sign the CertificateVerify data of an SSL client auth handshake with the client certificate's private key. Possible causes for this include the user implicitly or explicitly denying access to the private key, the private key may not be valid for signing, the key may be relying on a cached handle which is no longer valid, or the CSP won't allow arbitrary data to be signed. The message was too large for the transport. (for example a UDP message which exceeds size threshold). Websocket protocol error. Indicates that we are terminating the connection due to a malformed frame or other protocol violation. Returned when attempting to bind an address that is already in use. An operation failed because the SSL handshake has not completed. SSL peer's public key is invalid. The certificate didn't match the built-in public key pins for the host name. The pins are set in net/http/transport_security_state.cc and require that one of a set of public keys exist on the path from the leaf to the root. Server request for client certificate did not contain any types we support. An SSL peer sent us a fatal decrypt_error alert. This typically occurs when a peer could not correctly verify a signature (in CertificateVerify or ServerKeyExchange) or validate a Finished message. There are too many pending WebSocketJob instances, so the new job was not pushed to the queue. There are too many active SocketStream instances, so the new connect request was rejected. The SSL server certificate changed in a renegotiation. The SSL server sent us a fatal unrecognized_name alert. Failed to set the socket's receive buffer size as requested. Failed to set the socket's send buffer size as requested. Failed to set the socket's receive buffer size as requested, despite success return code from setsockopt. Failed to set the socket's send buffer size as requested, despite success return code from setsockopt. Failed to import a client certificate from the platform store into the SSL library. Resolving a hostname to an IP address list included the IPv4 address "127.0.53.53". This is a special IP address which ICANN has recommended to indicate there was a name collision, and alert admins to a potential problem. The SSL server presented a certificate which could not be decoded. This is not a certificate error code as no X509Certificate object is available. This error is fatal. Certificate Transparency: Received a signed tree head that failed to parse. Certificate Transparency: Received a signed tree head whose JSON parsing was OK but was missing some of the fields. The attempt to reuse a connection to send proxy auth credentials failed before the AuthController was used to generate credentials. The caller should reuse the controller with a new connection. This error is only used internally by the network stack. Certificate Transparency: Failed to parse the received consistency proof. The SSL server required an unsupported cipher suite that has since been removed. This error will temporarily be signaled on a fallback for one or two releases immediately following a cipher suite's removal, after which the fallback will be removed. When a WebSocket handshake is done successfully and the connection has been upgraded, the URLRequest is cancelled with this error code. Socket ReadIfReady support is not implemented. This error should not be user visible, because the normal Read() method is used as a fallback. No socket buffer space is available. There were no common signature algorithms between our client certificate private key and the server's preferences. TLS 1.3 early data was rejected by the server. This will be received before any data is returned from the socket. The request should be retried with early data disabled. TLS 1.3 early data was offered, but the server responded with TLS 1.2 or earlier. This is an internal error code to account for a backwards-compatibility issue with early data and TLS 1.2. It will be received before any data is returned from the socket. The request should be retried with early data disabled. See https://tools.ietf.org/html/rfc8446#appendix-D.3 for details. TLS 1.3 was enabled, but a lower version was negotiated and the server returned a value indicating it supported TLS 1.3. This is part of a security check in TLS 1.3, but it may also indicate the user is behind a buggy TLS-terminating proxy which implemented TLS 1.2 incorrectly. (See https://crbug.com/boringssl/226.) The server's certificate has a keyUsage extension incompatible with the negotiated TLS key exchange method. The server responded with a certificate whose common name did not match the host name. This could mean: 1. An attacker has redirected our traffic to his server and is presenting a certificate for which he knows the private key. 2. The server is misconfigured and responding with the wrong cert. 3. The user is on a wireless network and is being redirected to the network's login page. 4. The OS has used a DNS search suffix and the server doesn't have a certificate for the abbreviated name in the address bar. The server responded with a certificate that, by our clock, appears to either not yet be valid or to have expired. This could mean: 1. An attacker is presenting an old certificate for which he has managed to obtain the private key 2. The server is misconfigured and is not presenting a valid cert. 3. Our clock is wrong. The server responded with a certificate that is signed by an authority we don't trust. The could mean: 1. An attacker has substituted the real certificate for a cert that contains his public key and is signed by his cousin. 2. The server operator has a legitimate certificate from a CA we don't know about, but should trust. 3. The server is presenting a self-signed certificate, providing no defense against active attackers (but foiling passive attackers). The server responded with a certificate that contains errors. This error is not recoverable. MSDN describes this error as follows: "The SSL certificate contains errors." NOTE: It's unclear how this differs from ERR_CERT_INVALID. For consistency, use that code instead of this one from now on. The certificate has no mechanism for determining if it is revoked. In effect, this certificate cannot be revoked. Revocation information for the security certificate for this site is not available. This could mean: 1. An attacker has compromised the private key in the certificate and is blocking our attempt to find out that the cert was revoked. 2. The certificate is unrevoked, but the revocation server is busy or unavailable. The server responded with a certificate has been revoked. We have the capability to ignore this error, but it is probably not the thing to do. The server responded with a certificate that is invalid. This error is not recoverable. The server responded with a certificate that is signed using a weak signature algorithm. The host name specified in the certificate is not unique. The server responded with a certificate that contains a weak key (e.g. a too-small RSA key). The certificate claimed DNS names that are in violation of name constraints. The certificate's validity period is too long. Certificate Transparency was required for this connection, but the server did not provide CT information that complied with the policy. The certificate chained to a legacy Symantec root that is no longer trusted. https://g.co/chrome/symantecpkicerts The certificate is known to be used for interception by an entity other the device owner. The connection uses an obsolete version of SSL/TLS. Add new certificate error codes here. Update the value of CERT_END whenever you add a new certificate error code. The value immediately past the last certificate error code. The URL is invalid. The scheme of the URL is disallowed. The scheme of the URL is unknown. Attempting to load an URL resulted in too many redirects. Attempting to load an URL resulted in an unsafe redirect (e.g., a redirect to file:// is considered unsafe). Attempting to load an URL with an unsafe port number. These are port numbers that correspond to services, which are not robust to spurious input that may be constructed as a result of an allowed web construct (e.g., HTTP looks a lot like SMTP, so form submission to port 25 is denied). The server's response was invalid. Error in chunked transfer encoding. The server did not support the request method. The response was 407 (Proxy Authentication Required), yet we did not send the request to a proxy. The server closed the connection without sending any data. The headers section of the response is too large. The evaluation of the PAC script failed. The response was 416 (Requested range not satisfiable) and the server cannot satisfy the range requested. The identity used for authentication is invalid. Content decoding of the response body failed. An operation could not be completed because all network IO is suspended. FLIP data received without receiving a SYN_REPLY on the stream. Converting the response to target encoding failed. The server sent an FTP directory listing in a format we do not understand. There are no supported proxies in the provided list. There is a SPDY protocol error. Credentials could not be established during HTTP Authentication. An HTTP Authentication scheme was tried which is not supported on this machine. Detecting the encoding of the response failed. (GSSAPI) No Kerberos credentials were available during HTTP Authentication. An unexpected, but documented, SSPI or GSSAPI status code was returned. The environment was not set up correctly for authentication (for example, no KDC could be found or the principal is unknown. An undocumented SSPI or GSSAPI status code was returned. The HTTP response was too big to drain. The HTTP response contained multiple distinct Content-Length headers. SPDY Headers have been received, but not all of them - status or version headers are missing, so we're expecting additional frames to complete them. No PAC URL configuration could be retrieved from DHCP. This can indicate either a failure to retrieve the DHCP configuration, or that there was no PAC URL configured in DHCP. The HTTP response contained multiple Content-Disposition headers. The HTTP response contained multiple Location headers. SPDY server refused the stream. Client should retry. This should never be a user-visible error. SPDY server didn't respond to the PING message. The HTTP response body transferred fewer bytes than were advertised by the Content-Length header when the connection is closed. The HTTP response body is transferred with Chunked-Encoding, but the terminating zero-length chunk was never sent when the connection is closed. There is a QUIC protocol error. The HTTP headers were truncated by an EOF. The QUIC crytpo handshake failed. This means that the server was unable to read any requests sent, so they may be resent. Transport security is inadequate for the SPDY version. The peer violated SPDY flow control. The peer sent an improperly sized SPDY frame. Decoding or encoding of compressed SPDY headers failed. Proxy Auth Requested without a valid Client Socket Handle. HTTP_1_1_REQUIRED error code received on HTTP/2 session. HTTP_1_1_REQUIRED error code received on HTTP/2 session to proxy. The PAC script terminated fatally and must be reloaded. The server was expected to return an HTTP/1.x response, but did not. Rather than treat it as HTTP/0.9, this error is returned. Initializing content decoding failed. Received HTTP/2 RST_STREAM frame with NO_ERROR error code. This error should be handled internally by HTTP/2 code, and should not make it above the SpdyStream layer. The pushed stream claimed by the request is no longer available. A pushed stream was claimed and later reset by the server. When this happens, the request should be retried. An HTTP transaction was retried too many times due for authentication or invalid certificates. This may be due to a bug in the net stack that would otherwise infinite loop, or if the server or proxy continually requests fresh credentials or presents a fresh invalid certificate. Received an HTTP/2 frame on a closed stream. Client is refusing an HTTP/2 stream. A pushed HTTP/2 stream was claimed by a request based on matching URL and request headers, but the pushed response headers do not match the request. The server returned a non-2xx HTTP response code. Not that this error is only used by certain APIs that interpret the HTTP response itself. URLRequest for instance just passes most non-2xx response back as success. The certificate presented on a QUIC connection does not chain to a known root and the origin connected to is not on a list of domains where unknown roots are allowed. The cache does not have the requested entry. Unable to read from the disk cache. Unable to write to the disk cache. The operation is not supported for this entry. The disk cache is unable to open this entry. The disk cache is unable to create this entry. Multiple transactions are racing to create disk cache entries. This is an internal error returned from the HttpCache to the HttpCacheTransaction that tells the transaction to restart the entry-creation logic because the state of the cache has changed. The cache was unable to read a checksum record on an entry. This can be returned from attempts to read from the cache. It is an internal error, returned by the SimpleCache backend, but not by any URLRequest methods or members. The cache found an entry with an invalid checksum. This can be returned from attempts to read from the cache. It is an internal error, returned by the SimpleCache backend, but not by any URLRequest methods or members. Internal error code for the HTTP cache. The cache lock timeout has fired. Received a challenge after the transaction has read some data, and the credentials aren't available. There isn't a way to get them at that point. Internal not-quite error code for the HTTP cache. In-memory hints suggest that the cache entry would not have been useable with the transaction's current configuration (e.g. load flags, mode, etc.) The disk cache is unable to doom this entry. The disk cache is unable to open or create this entry. The server's response was insecure (e.g. there was a cert error). The server responded to a <keygen> with a generated client cert that we don't have the matching private key for. An error adding to the OS certificate database (e.g. OS X Keychain). An error occurred while handling a signed exchange. An error occurred while handling a Web Bundle source. A generic error for failed FTP control connection command.

If the `--no-referrers` command-line flag is specified then the policy value will be ignored and the Referrer value will never be sent. Must be kept synchronized with net::URLRequest::ReferrerPolicy from Chromium. Clear the referrer header if the header value is HTTPS but the request destination is HTTP. This is the default behavior. Default which is equivalent to A slight variant on : If the request destination is HTTP, an HTTPS referrer will be cleared. If the request's destination is cross-origin with the referrer (but does not downgrade), the referrer's granularity will be stripped down to an origin rather than a full URL. Same-origin requests will send the full referrer. Strip the referrer down to an origin when the origin of the referrer is different from the destination's origin. Never change the referrer. Strip the referrer down to the origin regardless of the redirect location. Clear the referrer when the request's referrer is cross-origin with the request's destination. Strip the referrer down to the origin, but clear it entirely if the referrer value is HTTPS and the destination is HTTP. Always clear the referrer regardless of the request destination. Always the last value in this enumeration. Resource type for a request. Top level page. Frame or iframe. CSS stylesheet. External script. Image (jpg/gif/png/etc). Font. Some other subresource. This is the default type if the actual type is unknown. Object (or embed) tag for a plugin, or a resource that a plugin requested. Media resource. Main resource of a dedicated worker.

An enum constant representing the QUIC option. Transition type for a request. Made up of one source value and 0 or more qualifiers. Source is a link click or the JavaScript window.open function. This is also the default value for requests like sub-resource loads that are not navigations. Source is some other "explicit" navigation. This is the default value for navigations where the actual type is unknown. See also . Source is a subframe navigation. This is any content that is automatically loaded in a non-toplevel frame. For example, if a page consists of several frames containing ads, those ad URLs will have this transition type. The user may not even realize the content in these pages is a separate frame, so may not care about the URL. Source is a subframe navigation explicitly requested by the user that will generate new navigation entries in the back/forward list. These are probably more important than frames that were automatically loaded in the background because the user probably cares about the fact that this link was loaded. Source is a form submission by the user. NOTE: In some situations submitting a form does not result in this transition type. This can happen if the form uses a script to submit the contents. Source is a "reload" of the page via the Reload function or by re-visiting the same URL. NOTE: This is distinct from the concept of whether a particular load uses "reload semantics" (i.e. bypasses cached data). General mask defining the bits used for the source values. Attempted to visit a URL but was blocked. Used the Forward or Back function to navigate among browsing history. Will be ORed to the transition type for the original load. Loaded a URL directly via CreateBrowser, LoadURL or LoadRequest. The beginning of a navigation chain. The last transition in a redirect chain. Redirects caused by JavaScript or a meta refresh tag on the page. Redirects sent from the server by HTTP headers. Used to test whether a transition involves a redirect. General mask defining the bits used for the qualifiers. Flags that represent CefURLRequest status. Unknown status. Request succeeded. An IO request is pending, and the caller will be informed when it is completed. Request was canceled programatically. Request failed for some reason. The manner in which a link click should be opened. An enum constant representing the unknown option. An enum constant representing the current tab option. Indicates that only one tab with the url should exist in the same window An enum constant representing the new foreground tab option. An enum constant representing the new background tab option. An enum constant representing the new popup option. An enum constant representing the new window option. An enum constant representing the save to disk option. An enum constant representing the off the record option. An enum constant representing the ignore action option. Event arguments for the AddressChanged event handler.

The methods of this class will be called on the CEF UI thread unless otherwise indicated. . Called on the CEF UI thread immediately after the CEF context has been initialized. You can now access the Global RequestContext through Cef.GetGlobalRequestContext() - this is the first place you can set Preferences (e.g. proxy settings, spell check dictionaries). Called from any thread when work has been scheduled for the browser process main (UI) thread. This callback is used in combination with CefSettings. ExternalMessagePump and Cef.DoMessageLoopWork() in cases where the CEF message loop must be integrated into an existing application message loop (see additional comments and warnings on Cef.DoMessageLoopWork). This callback should schedule a Cef.DoMessageLoopWork() call to happen on the main (UI) thread. is the requested delay in milliseconds. If delay is less than or equal to 0 then the call should happen reasonably soon. If delay is greater than 0 then the call should be scheduled to happen after the specified delay and any currently pending scheduled call should be cancelled. Implement this interface to handle context menu events. Called before a context menu is displayed. The model can be cleared to show no context menu or modified to show a custom menu. the ChromiumWebBrowser control the browser object The frame the request is coming from provides information about the context menu state initially contains the default context menu Called to execute a command selected from the context menu.

Called when an external drag event enters the browser window. the ChromiumWebBrowser control the browser object contains the drag event data represents the type of drag operation Return false for default drag handling behavior or true to cancel the drag event. Called whenever draggable regions for the browser window change. These can be specified using the '-webkit-app-region: drag/no-drag' CSS-property. If draggable regions are never defined in a document this method will also never be called. If the last draggable region is removed from a document this method will be called with an empty IList. the ChromiumWebBrowser control the browser object The frame List of objects or null if last region was removed. Implement this interface to handle events related to find results. The methods of this class will be called on the CEF UI thread. Called to report find results returned by the ChromiumWebBrowser control the browser object is the identifier passed to Find() is the number of matches currently identified is the location of where the match was found (in window coordinates) is the current position in the search results is true if this is the last find notification.

Return false to allow the focus to be set or true to cancel setting the focus. Called when the browser component is about to lose focus. For instance, if focus was on the last HTML element and the user pressed the TAB key. the ChromiumWebBrowser control the browser object Will be true if the browser is giving focus to the next component and false if the browser is giving focus to the previous component. Implement this interface to handle events related to JavaScript dialogs. The methods of this class will be called on the CEF UI thread. Called to run a JavaScript dialog. the ChromiumWebBrowser control the browser object originating url Dialog Type Message Text value will be specified for prompt dialogs only Callback can be executed inline or in an async fashion Set suppressMessage to true and return false to suppress the message (suppressing messages is preferable to immediately executing the callback as this is used to detect presumably malicious behavior like spamming alert messages in onbeforeunload). Set suppressMessage to false and return false to use the default implementation (the default implementation will show one modal dialog at a time and suppress any additional dialog requests until the displayed dialog is dismissed). Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute |callback| once the custom dialog is dismissed. Called to run a dialog asking the user if they want to leave a page. Return false to use the default dialog implementation. Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute once the custom dialog is dismissed. the ChromiumWebBrowser control the browser object message text (optional) indicates a page reload Callback can be executed inline or in an async fashion Return false to use the default dialog implementation otherwise return true to handle with your own custom implementation. Called to cancel any pending dialogs and reset any saved dialog state. Will be called due to events like page navigation irregardless of whether any dialogs are currently pending. the ChromiumWebBrowser control the browser object Called when the default implementation dialog is closed. the ChromiumWebBrowser control the browser object Implement this interface to handle events related to keyboard input. Called before a keyboard event is sent to the renderer. Return true if the event was handled or false otherwise. If the event will be handled in as a keyboard shortcut set isKeyboardShortcut to true and return false. the ChromiumWebBrowser control The browser instance. Whether this was a key up/down/raw/etc... The Windows key code for the key event. This value is used by the DOM specification. Sometimes it comes directly from the event (i.e. on Windows) and sometimes it's determined using a mapping function. See WebCore/platform/chromium/KeyboardCodes.h for the list of values. The native key code. On Windows this appears to be in the format of WM_KEYDOWN/WM_KEYUP/etc... lParam data. What other modifier keys are currently down: Shift/Control/Alt/OS X Command/etc... Indicates whether the event is considered a "system key" event (see http://msdn.microsoft.com/en-us/library/ms646286(VS.85).aspx for details). See the summary for an explanation of when to set this to true. Returns true if the event was handled or false otherwise. Called after the renderer and JavaScript in the page has had a chance to handle the event. Return true if the keyboard event was handled or false otherwise. the ChromiumWebBrowser control The browser instance. Whether this was a key up/down/raw/etc... The Windows key code for the key event. This value is used by the DOM specification. Sometimes it comes directly from the event (i.e. on Windows) and sometimes it's determined using a mapping function. See WebCore/platform/chromium/KeyboardCodes.h for the list of values. The native key code. On Windows this appears to be in the format of WM_KEYDOWN/WM_KEYUP/etc... lParam data. What other modifier keys are currently down: Shift/Control/Alt/OS X Command/etc... Indicates whether the event is considered a "system key" event (see http://msdn.microsoft.com/en-us/library/ms646286(VS.85).aspx for details). Return true if the keyboard event was handled or false otherwise. Implement this interface to handle events related to browser life span. The methods of this class will be called on the CEF UI thread unless otherwise indicated. Called before a popup window is created. the ChromiumWebBrowser control The browser instance that launched this popup. The HTML frame that launched this popup. The URL of the popup content. (This may be empty/null) The name of the popup. (This may be empty/null) The value indicates where the user intended to open the popup (e.g. current tab, new tab, etc) The value will be true if the popup was opened via explicit user gesture (e.g. clicking a link) or false if the popup opened automatically (e.g. via the DomContentLoaded event). structure contains additional information about the requested popup window window information browser settings, defaults to source browsers value indicates whether the new browser window should be scriptable and in the same process as the source browser. EXPERIMENTAL - A newly created browser that will host the popup. Set to null for default behaviour. To cancel creation of the popup window return true otherwise return false. CEF documentation: Called on the IO thread before a new popup window is created. The |browser| and |frame| parameters represent the source of the popup request. The |target_url| and |target_frame_name| values may be empty if none were specified with the request. The |popupFeatures| structure contains information about the requested popup window. To allow creation of the popup window optionally modify |windowInfo|, |client|, |settings| and |no_javascript_access| and return false. To cancel creation of the popup window return true. The |client| and |settings| values will default to the source browser's values. The |no_javascript_access| value indicates whether the new browser window should be scriptable and in the same process as the source browser. Called after a new browser is created. the ChromiumWebBrowser control The browser instance Called when a browser has recieved a request to close. This may result directly from a call to CefBrowserHost::CloseBrowser() or indirectly if the browser is a top-level OS window created by CEF and the user attempts to close the window. This method will be called after the JavaScript 'onunload' event has been fired. It will not be called for browsers after the associated OS window has been destroyed (for those browsers it is no longer possible to cancel the close). If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique. If an application provides its own top-level window it should handle OS close notifications by calling CefBrowserHost::CloseBrowser(false) instead of immediately closing (see the example below). This gives CEF an opportunity to process the 'onbeforeunload' event and optionally cancel the close before DoClose() is called. The CefLifeSpanHandler::OnBeforeClose() method will be called immediately before the browser object is destroyed. The application should only exit after OnBeforeClose() has been called for all existing browsers. If the browser represents a modal window and a custom modal loop implementation was provided in CefLifeSpanHandler::RunModal() this callback should be used to restore the opener window to a usable state. By way of example consider what should happen during window close when the browser is parented to an application-provided top-level OS window. 1. User clicks the window close button which sends an OS close notification (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). 2. Application's top-level window receives the close notification and: A. Calls CefBrowserHost::CloseBrowser(false). B. Cancels the window close. 3. JavaScript 'onbeforeunload' handler executes and shows the close confirmation dialog (which can be overridden via CefJSDialogHandler::OnBeforeUnloadDialog()). 4. User approves the close. 5. JavaScript 'onunload' handler executes. 6. Application's DoClose() handler is called. Application will: A. Set a flag to indicate that the next close attempt will be allowed. B. Return false. 7. CEF sends an OS close notification. 8. Application's top-level window receives the OS close notification and allows the window to close based on the flag from #6B. 9. Browser OS window is destroyed. 10. Application's CefLifeSpanHandler::OnBeforeClose() handler is called and the browser object is destroyed. 11. Application exits by calling CefQuitMessageLoop() if no other browsers exist. the ChromiumWebBrowser control The browser instance - check if IsDisposed as it's possible when the browser is disposing For default behaviour return false Called before a CefBrowser window (either the main browser for , or one of its children) the ChromiumWebBrowser control The browser instance Implement this interface to handle events related to browser load status. The methods of this interface will be called on the CEF UI thread. Blocking in these methods will likely cause your UI to become unresponsive and/or hang. Called when the loading state has changed. This callback will be executed twice once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang. the ChromiumWebBrowser control args Called when the browser begins loading a frame. The value will never be empty Check the method to see if this frame is the main frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use instead. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang. the ChromiumWebBrowser control args Whilst thist may seem like a logical place to execute js, it's called before the DOM has been loaded, implement as it's called when the underlying V8Context is created (Only called for the main frame at this stage) Called when the browser is done loading a frame. The value will never be empty Check the method to see if this frame is the main frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang. the ChromiumWebBrowser control args Called when the resource load for a navigation fails or is canceled. is the error code number, is the error text and is the URL that failed to load. See net\base\net_error_list.h for complete descriptions of the error codes. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang. the ChromiumWebBrowser control args Messages sent by the render process can be handled by implementing this interface. OnContextCreated is called in the Render process immediately after a CefV8Context is created. An IPC message is immediately sent to notify the context has been created (should be safe to execute javascript). If the page has no javascript then no V8Context will be created and as a result this method will not be called. Called for every V8Context. To determine if V8Context is from Main frame check The ChromiumWebBrowser control The browser object The frame. OnContextReleased is called in the Render process immediately before the CefV8Context is released. An IPC message is immediately sent to notify the context has been released (cannot execute javascript this point). If the page had no javascript then the context would not have been created and as a result this method will not be called. Called for every V8Context. To determine if V8Context is from Main frame check The ChromiumWebBrowser control The browser object The frame. Invoked when an element in the UI gains focus (or possibly no element gains focus; i.e. an element lost focus). The ChromiumWebBrowser control The browser object The frame object An object with information about the node (if any) that has focus. OnUncaughtException is called for global uncaught exceptions in a frame. Execution of this callback is disabled by default. To enable set CefSettings.UncaughtExceptionStackSize > 0. The ChromiumWebBrowser control The browser object The frame The exception object with the message and stacktrace. Implement this interface to provide handler implementations. The handler instance will not be released until all objects related to the context have been destroyed. Implement this interface to cancel loading of specific plugins Called immediately after the request context has been initialized. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. the request context Called on the CEF IO thread before a plugin instance is loaded. The default plugin policy can be set at runtime using the `--plugin-policy=[allow|detect|block]` command-line flag. is the mime type of the plugin that will be loaded is the content URL that the plugin will load and may be empty will be true if the plugin is being loaded in the main (top-level) frame is the URL for the top-level frame that contains the plugin includes additional information about the plugin that will be loaded Modify and return true to change the policy. Return false to use the recommended policy. Modify and return true to change the policy. Called on the CEF IO thread before a resource request is initiated. This method will not be called if the client associated with returns a non-NULL value from for the same request (identified by ). represent the source browser of the request, and may be null for requests originating from service workers. represent the source frame of the request, and may be null for requests originating from service workers. represents the request contents and cannot be modified in this callback will be true if the resource request is a navigation will be true if the resource request is a download is the origin (scheme + domain) of the page that initiated the request Set to true to disable default handling of the request, in which case it will need to be handled via or it will be canceled To allow the resource load to proceed with default handling return null. To specify a handler for the resource return a object. Implement this interface to handle events related to browser requests. The methods of this class will be called on the thread indicated. Called before browser navigation. If the navigation is allowed and will be called. If the navigation is canceled will be called with an ErrorCode value of . the ChromiumWebBrowser control the browser object The frame the request is coming from the request object - cannot be modified in this callback The value will be true if the browser navigated via explicit user gesture (e.g. clicking a link) or false if it navigated automatically (e.g. via the DomContentLoaded event). has the request been redirected Return true to cancel the navigation or false to allow the navigation to proceed. Called on the CEF UI thread when the window.document object of the main frame has been created. the ChromiumWebBrowser control the browser object Called on the UI thread before OnBeforeBrowse in certain limited cases where navigating a new or different browser might be desirable. This includes user-initiated navigation that might open in a special way (e.g. links clicked via middle-click or ctrl + left-click) and certain types of cross-origin navigation initiated from the renderer process (e.g. navigating the top-level frame to/from a file URL). the ChromiumWebBrowser control the browser object The frame object target url The value indicates where the user intended to navigate the browser based on standard Chromium behaviors (e.g. current tab, new tab, etc). The value will be true if the browser navigated via explicit user gesture (e.g. clicking a link) or false if it navigated automatically (e.g. via the DomContentLoaded event). Return true to cancel the navigation or false to allow the navigation to proceed in the source browser's top-level frame. Called on the CEF IO thread before a resource request is initiated. the ChromiumWebBrowser control represent the source browser of the request represent the source frame of the request represents the request contents and cannot be modified in this callback will be true if the resource request is a navigation will be true if the resource request is a download is the origin (scheme + domain) of the page that initiated the request to true to disable default handling of the request, in which case it will need to be handled via or it will be canceled To allow the resource load to proceed with default handling return null. To specify a handler for the resource return a object. If this callback returns null the same method will be called on the associated , if any Called when the browser needs credentials from the user. The ChromiumWebBrowser control the browser object is the origin making this authentication request indicates whether the host is a proxy server hostname port number realm scheme Callback interface used for asynchronous continuation of authentication requests. Return true to continue the request and call when the authentication information is available. Return false to cancel the request. Called when JavaScript requests a specific storage quota size via the webkitStorageInfo.requestQuota function. For async processing return true and execute at a later time to grant or deny the request or to cancel. The ChromiumWebBrowser control the browser object the origin of the page making the request is the requested quota size in bytes Callback interface used for asynchronous continuation of url requests. Return false to cancel the request immediately. Return true to continue the request and call either in this method or at a later time to grant or deny the request. Called to handle requests for URLs with an invalid SSL certificate. Return true and call either in this method or at a later time to continue or cancel the request. If CefSettings.IgnoreCertificateErrors is set all invalid certificates will be accepted without calling this method. the ChromiumWebBrowser control the browser object the error code for this invalid certificate the url of the request for the invalid certificate ssl certificate information Callback interface used for asynchronous continuation of url requests. If empty the error cannot be recovered from and the request will be canceled automatically. Return false to cancel the request immediately. Return true and use to execute in an async fashion. Called when the browser needs user to select Client Certificate for authentication requests (eg. PKI authentication). The ChromiumWebBrowser control the browser object indicates whether the host is a proxy server hostname port number List of Client certificates for selection Callback interface used for asynchronous continuation of client certificate selection for authentication requests. Return true to continue the request and call ISelectClientCertificateCallback.Select() with the selected certificate for authentication. Return false to use the default behavior where the browser selects the first certificate from the list. Called when a plugin has crashed the ChromiumWebBrowser control the browser object path of the plugin that crashed Called on the CEF UI thread when the render view associated with browser is ready to receive/handle IPC messages in the render process. The ChromiumWebBrowser control the browser object Called when the render process terminates unexpectedly. The ChromiumWebBrowser control the browser object indicates how the process terminated. Class used to implement a custom resource handler. The methods of this class will always be called on the CEF IO thread. Blocking the CEF IO thread will adversely affect browser performance. We suggest you execute your code in a Task (or similar). To implement async handling, spawn a new Task (or similar), keep a reference to the callback. When you have a fully populated stream, execute the callback. Once the callback Executes, GetResponseHeaders will be called where you can modify the response including headers, or even redirect to a new Url. Set your responseLength and headers Populate the dataOut stream in ReadResponse. For those looking for a sample implementation or upgrading from a previous version . For those upgrading, inherit from ResourceHandler instead of IResourceHandler add the override keyword to existing methods e.g. ProcessRequestAsync. Open the response stream. - To handle the request immediately set to true and return true. - To decide at a later time set to false, return true, and execute to continue or cancel the request. - To cancel the request immediately set to true and return false. This method will be called in sequence but not from a dedicated thread. For backwards compatibility set to false and return false and the method will be called. request see main summary callback see main summary Begin processing the request. The request object. The callback used to Continue or Cancel the request (async). To handle the request return true and call once the response header information is available can also be called from inside this method if header information is available immediately). To cancel the request return false. Retrieve response header information. If the response length is not known set to -1 and ReadResponse() will be called until it returns false. If the response length is known set to a positive value and ReadResponse() will be called until it returns false or the specified number of bytes have been read. It is also possible to set to a redirect http status code and pass the new URL via a Location header. Likewise with it is valid to set a relative or fully qualified URL as the Location header value. If an error occured while setting up the request you can call on to indicate the error condition. Use the response object to set the mime type, http status code and other optional header values. If the response length is not known set responseLength to -1 To redirect the request to a new URL set this to the new URL. Can be either a relative or fully qualified URL. Skip response data when requested by a Range header. Skip over and discard bytesToSkip bytes of response data. - If data is available immediately set bytesSkipped to the number of of bytes skipped and return true. - To read the data at a later time set bytesSkipped to 0, return true and execute callback when the data is available. - To indicate failure set bytesSkipped to < 0 (e.g. -2 for ERR_FAILED) and return false. This method will be called in sequence but not from a dedicated thread. number of bytes to be skipped If data is available immediately set bytesSkipped to the number of of bytes skipped and return true. To read the data at a later time set bytesSkipped to 0, return true and execute callback when the data is available. To read the data at a later time set bytesSkipped to 0, return true and execute callback when the data is available. See summary Read response data. If data is available immediately copy up to dataOut.Length bytes into dataOut, set bytesRead to the number of bytes copied, and return true. To read the data at a later time keep a pointer to dataOut, set bytesRead to 0, return true and execute callback when the data is available (dataOut will remain valid until the callback is executed). To indicate response completion set bytesRead to 0 and return false. To indicate failure set bytesRead to < 0 (e.g. -2 for ERR_FAILED) and return false. This method will be called in sequence but not from a dedicated thread. For backwards compatibility set bytesRead to -1 and return false and the ReadResponse method will be called. If data is available immediately copy up to bytes into dataOut. To indicate response completion set bytesRead to 0 and return false. set to 0, return true and execute callback when the data is available (dataOut will remain valid until the callback is executed). If you have no need of the callback then Dispose of it immediately. return true or false depending on the criteria, see summary. Read response data. If data is available immediately copy to dataOut, set bytesRead to the number of bytes copied, and return true. To read the data at a later time set bytesRead to 0, return true and call ICallback.Continue() when the data is available. To indicate response completion return false. Stream to write to Number of bytes copied to the stream The callback used to Continue or Cancel the request (async). If data is available immediately copy to dataOut, set bytesRead to the number of bytes copied, and return true.To indicate response completion return false. Depending on this size of your response this method may be called multiple times Request processing has been canceled. Interface representing browser initialization settings.

Opaque background color used for the browser before a document is loaded and when no document color is specified. By default the background color will be the same as CefSettings.BackgroundColor. Only the RGB compontents of the specified value will be used. The alpha component must greater than 0 to enable use of the background color but will be otherwise ignored. Comma delimited ordered list of language codes without any whitespace that will be used in the "Accept-Language" HTTP header. May be overridden on a per-browser basis using the CefBrowserSettings.AcceptLanguageList value. If both values are empty then "en-US,en" will be used. Can be overridden for individual RequestContext instances via the RequestContextSettings.AcceptLanguageList value. The maximum rate in frames per second (fps) that CefRenderHandler::OnPaint will be called for a windowless browser. The actual fps may be lower if the browser cannot generate frames at the requested rate. The minimum value is 1 and the maximum value is 60 (default 30). This value can also be changed dynamically via IBrowserHost.SetWindowlessFrameRate. Gets a value indicating if the browser settings has been disposed. Gets a value indicating if the browser settings instance was created internally by CefSharp. Instances created by CefSharp will be Disposed of after use. To control the lifespan yourself create an set BrowserSettings yourself. Used internally to get the underlying instance. Unlikely you'll use this yourself. the inner most instance Represents the tag name and attribute data belonging to a node in the browser's DOM. Get the value of an attribute.

A request context provides request handling for a set of related browser or URL request objects. A request context can be specified when creating a new browser by setting the property (Passing in via the constructor for the OffScreen control is preferred). Browser objects with different request contexts will never be hosted in the same render process. Browser objects with the same request context may or may not be hosted in the same render process depending on the process model.Browser objects created indirectly via the JavaScript window.open function or targeted links will share the same render process and the same request context as the source browser. Gets a value indicating whether the RequestContext has been disposed of. Returns true if this object is pointing to the same context object. context to compare Returns true if the same Returns true if this object is sharing the same storage as the specified context. context to compare Returns true if same storage Returns true if this object is the global context. The global context is used by default when creating a browser or URL request with a NULL context argument. Returns the default cookie manager for this object. This will be the global cookie manager if this object is the global request context. If callback is non-NULL it will be executed asynchronously on the CEF IO thread after the manager's storage has been initialized. Returns the default cookie manager for this object Register a scheme handler factory for the specified schemeName and optional domainName. An empty domainName value for a standard scheme will cause the factory to match all domain names. The domainName value will be ignored for non-standard schemes. If schemeName is a built-in scheme and no handler is returned by factory then the built-in scheme handler factory will be called. If schemeName is a custom scheme then you must also implement the CefApp::OnRegisterCustomSchemes() method in all processes. This function may be called multiple times to change or remove the factory that matches the specified schemeName and optional domainName. Scheme Name Optional domain name Scheme handler factory Returns false if an error occurs. Clear all registered scheme handler factories. Returns false on error. Returns the cache path for this object. If empty an "incognito mode" in-memory cache is being used. Tells all renderer processes associated with this context to throw away their plugin list cache. If reloadPages is true they will also reload all pages with plugins. RequestContextHandler.OnBeforePluginLoad may be called to rebuild the plugin list cache. reload any pages with pluginst Returns true if a preference with the specified name exists. This method must be called on the CEF UI thread. name of preference bool if the preference exists Use Cef.UIThreadTaskFactory to execute this method if required, and ChromiumWebBrowser.IsBrowserInitializedChanged are both executed on the CEF UI thread, so can be called directly. When CefSettings.MultiThreadedMessageLoop == false (the default is true) then the main application thread will be the CEF UI thread. Returns the value for the preference with the specified name. Returns NULL if the preference does not exist. The returned object contains a copy of the underlying preference value and modifications to the returned object will not modify the underlying preference value. This method must be called on the CEF UI thread. preference name Returns the value for the preference with the specified name Use Cef.UIThreadTaskFactory to execute this method if required, and ChromiumWebBrowser.IsBrowserInitializedChanged are both executed on the CEF UI thread, so can be called directly. When CefSettings.MultiThreadedMessageLoop == false (the default is true) then the main application thread will be the CEF UI thread. Returns all preferences as a dictionary. The returned object contains a copy of the underlying preference values and modifications to the returned object will not modify the underlying preference values. This method must be called on the browser process UI thread. If true then preferences currently at their default value will be included. Preferences (dictionary can have sub dictionaries) Returns true if the preference with the specified name can be modified using SetPreference. As one example preferences set via the command-line usually cannot be modified. This method must be called on the CEF UI thread. preference key Returns true if the preference with the specified name can be modified using SetPreference Use Cef.UIThreadTaskFactory to execute this method if required, and ChromiumWebBrowser.IsBrowserInitializedChanged are both executed on the CEF UI thread, so can be called directly. When CefSettings.MultiThreadedMessageLoop == false (the default is true) then the main application thread will be the CEF UI thread. Set the value associated with preference name. If value is null the preference will be restored to its default value. If setting the preference fails then error will be populated with a detailed description of the problem. This method must be called on the CEF UI thread. Preferences set via the command-line usually cannot be modified. preference key preference value out error Returns true if the value is set successfully and false otherwise. Use Cef.UIThreadTaskFactory to execute this method if required, and ChromiumWebBrowser.IsBrowserInitializedChanged are both executed on the CEF UI thread, so can be called directly. When CefSettings.MultiThreadedMessageLoop == false (the default is true) then the main application thread will be the CEF UI thread. Clears all certificate exceptions that were added as part of handling . If you call this it is recommended that you also call or you risk not being prompted again for server certificates if you reconnect quickly. If is non-NULL it will be executed on the CEF UI thread after completion. This param is optional Clears all HTTP authentication credentials that were added as part of handling . If is non-NULL it will be executed on the CEF UI thread after completion. This param is optional Clears all active and idle connections that Chromium currently has. This is only recommended if you have released all other CEF objects but don't yet want to call Cef.Shutdown(). If is non-NULL it will be executed on the CEF UI thread after completion. This param is optional Attempts to resolve origin to a list of associated IP addresses. host name to resolve A task that represents the Resoolve Host operation. The value of the TResult parameter contains ResolveCallbackResult. Returns true if this context was used to load the extension identified by extensionId. Other contexts sharing the same storage will also have access to the extension (see HasExtension). This method must be called on the CEF UI thread. Returns true if this context was used to load the extension identified by extensionId Returns the extension matching extensionId or null if no matching extension is accessible in this context (see HasExtension). This method must be called on the CEF UI thread. extension Id Returns the extension matching extensionId or null if no matching extension is accessible in this context Retrieve the list of all extensions that this context has access to (see HasExtension). will be populated with the list of extension ID values. This method must be called on the CEF UI thread. output a list of extensions Ids returns true on success otherwise false Returns true if this context has access to the extension identified by extensionId. This may not be the context that was used to load the extension (see DidLoadExtension). This method must be called on the CEF UI thread. extension id Returns true if this context has access to the extension identified by extensionId Load an extension. If extension resources will be read from disk using the default load implementation then rootDirectoy should be the absolute path to the extension resources directory and manifestJson should be null. If extension resources will be provided by the client (e.g. via IRequestHandler and/or IExtensionHandler) then rootDirectory should be a path component unique to the extension (if not absolute this will be internally prefixed with the PK_DIR_RESOURCES path) and manifestJson should contain the contents that would otherwise be read from the "manifest.json" file on disk. The loaded extension will be accessible in all contexts sharing the same storage (HasExtension returns true). However, only the context on which this method was called is considered the loader (DidLoadExtension returns true) and only the loader will receive IRequestContextHandler callbacks for the extension. will be called on load success or will be called on load failure. If the extension specifies a background script via the "background" manifest key then will be called to create the background browser. See that method for additional information about background scripts. For visible extension views the client application should evaluate the manifest to determine the correct extension URL to load and then load the extension URL in a ChromiumWebBrowser instance after the extension has loaded. For example, the client can look for the "browser_action" manifest key as documented at https://developer.chrome.com/extensions/browserAction. Extension URLs take the form "chrome-extension://<extension_id>/<path>" Browsers that host extensions differ from normal browsers as follows: - Can access chrome.* JavaScript APIs if allowed by the manifest. Visit chrome://extensions-support for the list of extension APIs currently supported by CEF. - Main frame navigation to non-extension content is blocked. - Pinch-zooming is disabled. - returns the hosted extension. - CefBrowserHost::IsBackgroundHost returns true for background hosts. See https://developer.chrome.com/extensions for extension implementation and usage documentation. If extension resources will be read from disk using the default load implementation then rootDirectoy should be the absolute path to the extension resources directory and manifestJson should be null If extension resources will be provided by the client then rootDirectory should be a path component unique to the extension and manifestJson should contain the contents that would otherwise be read from the manifest.json file on disk handle events related to browser extensions For extensions that load a popup you are required to query the Manifest, build a Url in the format chrome-extension://{extension.Identifier}/{default_popup} with default_popup url coming from the mainfest. With the extension url you then need to open a new Form/Window/Tab and create a new ChromiumWebBrowser instance to host the extension popup. To load a crx file you must first unzip them to a folder and pass the path containing the extension as . It in theory should be possible to load a crx file in memory, passing it's manifest.json file content as then fulfilling the resource rquests made to . Used internally to get the underlying instance. Unlikely you'll use this yourself. the inner most instance Implement this interface to filter resource response content. The methods of this class will be called on the CEF IO thread. Initialize the response filter. Will only be called a single time. The filter will not be installed if this method returns false. The filter will not be installed if this method returns false. Called to filter a chunk of data. This method will be called repeatedly until there is no more data to filter (resource response is complete), dataInRead matches dataIn.Length (all available pre-filter bytes have been read), and the method returns FilterStatus.Done or FilterStatus.Error. is a Stream wrapping the underlying input buffer containing pre-filter data. Can be null. Set to the number of bytes that were read from dataIn is a Stream wrapping the underlying output buffer that can accept filtered output data. Check dataOut.Length for maximum buffer size Set to the number of bytes that were written into dataOut If some or all of the pre-filter data was read successfully but more data is needed in order to continue filtering (filtered output is pending) return FilterStatus.NeedMoreData. If some or all of the pre-filter data was read successfully and all available filtered output has been written return FilterStatus.Done. If an error occurs during filtering return FilterStatus.Error.

Set to true to print background graphics or false to not print background graphics. Used for managing cookies. The methods may be called on any thread unless otherwise indicated. Delete all cookies that match the specified parameters. If both and values are specified all host and domain cookies matching both will be deleted. If only is specified all host cookies (but not domain cookies) irrespective of path will be deleted. If is empty all cookies for all hosts and domains will be deleted. Cookies can alternately be deleted using the Visit*Cookies() methods. The cookie URL. The name of the cookie. If non-NULL it will be executed asynchronously on the CEF UI thread after the cookies have been deleted. Returns false if a non-empty invalid URL is specified or if cookies cannot be accessed; otherwise, true. Sets a cookie given a valid URL and explicit user-provided cookie attributes. This function expects each attribute to be well-formed. It will check for disallowed characters (e.g. the ';' character is disallowed within the cookie value attribute) and fail without setting the cookie if such characters are found. This method will be executed on the CEF UI thread in an async fashion, to be notified upon completion implement and pass in as The cookie URL The cookie If non-NULL it will be executed asynchronously on the CEF UI thread after the cookie has been set. Returns false if an invalid URL is specified or if cookies cannot be accessed. Visit all cookies on the UI thread. The returned cookies are ordered by longest path, then by earliest creation date. A user-provided Cookie Visitor implementation. Returns false if cookies cannot be accessed; otherwise, true. Visit a subset of cookies on the CEF UI thread.

Bit flags describing any pressed modifier keys. See cef_event_flags_t for values. The Windows key code for the key event. This value is used by the DOM specification. Sometimes it comes directly from the event (i.e. on Windows) and sometimes it's determined using a mapping function. See WebCore/platform/chromium/KeyboardCodes.h for the list of values. The actual key code genenerated by the platform. Indicates whether the event is considered a "system key" event (see http://msdn.microsoft.com/en-us/library/ms646286(VS.85).aspx for details). This value will always be false on non-Windows platforms. True if the focus is currently on an editable field on the page. This is useful for determining if standard key events should be intercepted.

Remove the specified . element to be removed. Returns true if the add succeeds. Retrieve the post data elements. Returns true if this object is read-only. Remove all existing post data elements. Gets a value indicating whether the object has been disposed of. Create a new instance PostDataElement Returns true if the underlying POST data includes elements that are not represented by this IPostData object (for example, multi-part file upload data). Modifying IPostData objects with excluded elements may result in the request failing. Used internally to get the underlying instance. Unlikely you'll use this yourself. the inner most instance Class used to represent a single element in the request post data. The methods of this class may be called on any thread. Gets or sets the file name. Gets if the object is read-only. Remove all contents from the post data element. Gets the type of this . Gets or sets the bytes of this . Used internally to get the underlying instance. Unlikely you'll use this yourself. the inner most instance Use this static class to configure some CefSharp specific settings like WcfTimeout Set default values for CefSharpSettings WCF is used by JavascriptObjectRepository.Register(isAsync: false) feature for Javascript Binding. It's recomended that anyone developing a new application use the JavascriptObjectRepository.Register(isAsync: true) version which communicates using native Chromium IPC. Change the Close timeout for the WCF channel used by the sync JSB binding. The default value is currently 2 seconds. Changing this to will result on Abort() being called on the WCF Channel Host For the WinForms and WPF instances of ChromiumWebBrowser the relevant Application Exit event is hooked and Cef.Shutdown() called by default. Set this to false to disable this behaviour. This value needs to be set before the first instance of ChromiumWebBrowser is created as the event handlers are hooked in the static constructor for the ChromiumWebBrowser class CefSharp.BrowserSubprocess will monitor the parent process and exit if the parent process closes before the subprocess. This currently defaults to true. See https://github.com/cefsharp/CefSharp/issues/2359 for more information. The proxy options that will be used for all connections If set before the call to Cef.Initialize, command line arguments will be set for you If a username and password is provided and the IPs match authentication is done automatically NOTE: GetAuthCredentials won't be called for a proxy server that matches the IP NOTE: It isn't possble to change the proxy after the call to Cef.Initialize This influences the behavior of how methods are executed for objects registered using . By default the queues Tasks for execution in a sequential order. A single method is exeucted at a time. Setting this property to true allows for concurrent task execution. Method calls are executed on (ThreadPool). If true a message will be sent from the render subprocess to the browser when a DOM node (or no node) gets focus. The default is false. Class used to Represent a cookie. The built in .Net Cookie class isn't used as some of it's properties have internal setters The cookie name The cookie value.

This method will return true if called on the CEF UI thread and the message was successfully submitted for validation, otherwise false. Validation will be applied asynchronously and any messages that fail due to formatting errors or missing parameters may be discarded without notification. Prefer ExecuteDevToolsMethod if a more structured approach to message formatting is desired. Every valid method call will result in an asynchronous method result or error message that references the sent message "id". Event messages are received while notifications are enabled (for example, between method calls for "Page.enable" and "Page.disable"). All received messages will be delivered to the observer(s) registered with AddDevToolsMessageObserver. See documentation for details of received message contents. Usage of the SendDevToolsMessage, ExecuteDevToolsMethod and AddDevToolsMessageObserver methods does not require an active DevTools front-end or remote-debugging session. Other active DevTools sessions will continue to function independently. However, any modification of global browser state by one session may not be reflected in the UI of other sessions. Communication with the DevTools front-end (when displayed) can be logged for development purposes by passing the `--devtools-protocol-log-file=<path>` command-line flag. must be a UTF8-encoded JSON dictionary that contains "id" (int), "method" (string) and "params" (dictionary, optional) values.

Call this method each time the mouse is moved across the web view during a drag operation (after calling and before calling /). This method is only used when window rendering is disabled. Call this method when the user completes the drag operation by dropping the object onto the web view (after calling ). The object being dropped is , given as an argument to the previous call. This method is only used when window rendering is disabled. Call this method when the drag operation started by a call has ended either in a drop or by being cancelled. If the web view is both the drag source and the drag target then all DragTarget* methods should be called before DragSource* methods. This method is only used when window rendering is disabled. x mouse coordinate relative to the upper-left corner of the view. y mouse coordinate relative to the upper-left corner of the view. Drag Operations mask Call this method when the user drags the mouse out of the web view (after calling ). This method is only used when window rendering is disabled. Call this method when the drag operation started by a call has completed. This method may be called immediately without first calling DragSourceEndedAt to cancel a drag operation. If the web view is both the drag source and the drag target then all DragTarget* methods should be called before DragSource* mthods. This method is only used when window rendering is disabled. Search for . must be a unique ID and these IDs must strictly increase so that newer requests always have greater IDs than older requests. If identifier is zero or less than the previous ID value then it will be automatically assigned a new valid ID. text to search for indicates whether to search forward or backward within the page indicates whether the search should be case-sensitive indicates whether this is the first request or a follow-up The instance, if any, will be called to report find results. Returns the extension hosted in this browser or null if no extension is hosted. See for details. Retrieve the window handle of the browser that opened this browser. The handler Retrieve the window handle for this browser. The handler Gets the current zoom level. The default zoom level is 0.0. This method can only be called on the CEF UI thread. zoom level (default is 0.0) Get the current zoom level. The default zoom level is 0.0. This method executes GetZoomLevel on the CEF UI thread in an async fashion. a that when executed returns the zoom level as a double. Invalidate the view. The browser will call CefRenderHandler::OnPaint asynchronously. This method is only used when window rendering is disabled (OSR). indicates which surface to re-paint either View or Popup. Returns true if this browser is hosting an extension background script. Background hosts do not have a window and are not displayable. See for details. Returns true if this browser is hosting an extension background script. Begins a new composition or updates the existing composition. Blink has a special node (a composition node) that allows the input method to change text without affecting other DOM nodes. This method may be called multiple times as the composition changes. When the client is done making changes the composition should either be canceled or completed. To cancel the composition call ImeCancelComposition. To complete the composition call either ImeCommitText or ImeFinishComposingText. Completion is usually signaled when: The client receives a WM_IME_COMPOSITION message with a GCS_RESULTSTR flag (on Windows). This method is only used when window rendering is disabled. (WPF and OffScreen) is the optional text that will be inserted into the composition node is an optional set of ranges that will be underlined in the resulting text. is an optional range of the existing text that will be replaced. (MAC OSX ONLY) is an optional range of the resulting text that will be selected after insertion or replacement. Completes the existing composition by optionally inserting the specified text into the composition node. This method is only used when window rendering is disabled. (WPF and OffScreen) text that will be committed is an optional range of the existing text that will be replaced. (MAC OSX ONLY) is where the cursor will be positioned relative to the current cursor position. (MAC OSX ONLY) Completes the existing composition by applying the current composition node contents. See comments on ImeSetComposition for usage. This method is only used when window rendering is disabled. (WPF and OffScreen) If keepSelection is false the current selection, if any, will be discarded. Cancels the existing composition and discards the composition node contents without applying them. See comments on ImeSetComposition for usage. This method is only used when window rendering is disabled. (WPF and OffScreen) Notify the browser that the window hosting it is about to be moved or resized. This will dismiss any existing popups (dropdowns). Send a notification to the browser that the screen info has changed. The browser will then call CefRenderHandler::GetScreenInfo to update the screen information with the new values. This simulates moving the webview window from one display to another, or changing the properties of the current display. This method is only used when window rendering is disabled. Print the current browser contents. Asynchronously prints the current browser contents to the Pdf file specified. The caller is responsible for deleting the file when done. Output file location. Print Settings, can be null Callback executed when printing complete If a misspelled word is currently selected in an editable node calling this method will replace it with the specified word. word to be replaced Call to run a file chooser dialog. Only a single file chooser dialog may be pending at any given time. The dialog will be initiated asynchronously on the CEF UI thread. represents the type of dialog to display to the title to be used for the dialog and may be empty to show the default title ("Open" or "Save" depending on the mode) is the path with optional directory and/or file name component that will be initially selected in the dialog are used to restrict the selectable file types and may any combination of (a) valid lower-cased MIME types (e.g. "text/*" or "image/*"), (b) individual file extensions (e.g. ".txt" or ".png"), or (c) combined description and file extension delimited using "|" and ";" (e.g. "Image Types|.png;.gif;.jpg") is the 0-based index of the filter that will be selected by default will be executed after the dialog is dismissed or immediately if another dialog is already pending. Returns the request context for this browser. Issue a BeginFrame request to Chromium. Only valid when is set to true. Send a capture lost event to the browser. Send a focus event to the browser. .

Send a touch event to the browser. WPF and OffScreen browsers only touch event Set accessibility state for all frames. If accessibilityState is Default then accessibility will be disabled by default and the state may be further controlled with the "force-renderer-accessibility" and "disable-renderer-accessibility" command-line switches. If accessibilityState is STATE_ENABLED then accessibility will be enabled. If accessibilityState is STATE_DISABLED then accessibility will be completely disabled. For windowed browsers accessibility will be enabled in Complete mode (which corresponds to kAccessibilityModeComplete in Chromium). In this mode all platform accessibility objects will be created and managed by Chromium's internal implementation. The client needs only to detect the screen reader and call this method appropriately. For example, on Windows the client can handle WM_GETOBJECT with OBJID_CLIENT to detect accessibility readers. For windowless browsers accessibility will be enabled in TreeOnly mode (which corresponds to kAccessibilityModeWebContentsOnly in Chromium). In this mode renderer accessibility is enabled, the full tree is computed, and events are passed to IAccessibiltyHandler, but platform accessibility objects are not created. The client may implement platform accessibility objects using IAccessibiltyHandler callbacks if desired. may be default, enabled or disabled. Enable notifications of auto resize via IDisplayHandler.OnAutoResize. Notifications are disabled by default. enable auto resize minimum size maximum size Set whether the browser is focused. (Used for Normal Rendering e.g. WinForms) set focus Change the zoom level to the specified value. Specify 0.0 to reset the zoom level. If called on the CEF UI thread the change will be applied immediately. Otherwise, the change will be applied asynchronously on the UI thread. zoom level Open developer tools in its own window.

Layouting and rendering notification will stop when the browser is hidden. This method is only used when window rendering is disabled (WPF/OffScreen). Notify the browser that the widget has been resized. The browser will first call CefRenderHandler::GetViewRect to get the new size and then call CefRenderHandler::OnPaint asynchronously with the updated regions. This method is only used when window rendering is disabled. Retrieve a snapshot of current navigation entries as values sent to the specified visitor. visitor If true only the current navigation entry will be sent, otherwise all navigation entries will be sent. Returns the current visible navigation entry for this browser. This method can only be called on the CEF UI thread which by default is not the same as your application UI thread. the current navigation entry Gets/sets the maximum rate in frames per second (fps) that CefRenderHandler:: OnPaint will be called for a windowless browser. The actual fps may be lower if the browser cannot generate frames at the requested rate. The minimum value is 1 and the maximum value is 60 (default 30). This method can only be called on the UI thread. Can also be set at browser creation via BrowserSettings.WindowlessFrameRate. Returns true if window rendering is disabled. Set whether the browser's audio is muted. true or false Returns true if the browser's audio is muted. This method can only be called on the CEF UI thread.

Execute select all in this frame. Save this frame's HTML source to a temporary file and open it in the default text viewing application. This method can only be called from the browser process. Retrieve this frame's HTML source as a string sent to the specified visitor. a that when executed returns this frame's HTML source as a string. Retrieve this frame's HTML source as a string sent to the specified visitor. Use the method for a Task based async wrapper visitor will receive string values asynchronously Retrieve this frame's display text as a string sent to the specified visitor. a that when executed returns the frame's display text as a string. Retrieve this frame's display text as a string sent to the specified visitor. Use the method for a Task based async wrapper visitor will receive string values asynchronously Load the custom request. LoadRequest can only be used if a renderer process already exists. In newer versions initially loading about:blank no longer creates a renderer process. You can load a Data Uri initially then call this method. https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs WARNING: This method will fail with "bad IPC message" reason INVALID_INITIATOR_ORIGIN (213) unless you first navigate to the request origin using some other mechanism (LoadURL, link click, etc). request to be loaded in the frame Load the specified url. url to be loaded in the frame Execute a string of JavaScript code in this frame.

Returns true if this is the focused frame. Returns the name for this frame. If the frame has an assigned name (for example, set via the iframe "name" attribute) then that value will be returned. Otherwise a unique name will be constructed based on the frame parent hierarchy. The main (top-level) frame will always have an empty name value. Returns the globally unique identifier for this frame or < 0 if the underlying frame does not yet exist. Returns the parent of this frame or NULL if this is the main (top-level) frame. Returns the URL currently loaded in this frame. Returns the browser that this frame belongs to. Gets a value indicating whether the frame has been disposed of. Create a custom request for use with Initialize the PostData object when creating this request A new instance of the request Create a new URL request that will be treated as originating from this frame and the associated browser. This request may be intercepted by the client via or . Use IUrlRequest.Create instead if you do not want the request to have this association, in which case it may be handled differently (see documentation on that method). Requests may originate from both the browser process and the render process. For requests originating from the browser process: - POST data may only contain a single element of type PDE_TYPE_FILE or PDE_TYPE_BYTES. For requests originating from the render process: - POST data may only contain a single element of type PDE_TYPE_BYTES. - If the response contains Content-Disposition or Mime-Type header values that would not normally be rendered then the response may receive special handling inside the browser for example, via the file download code path instead of the URL request code path).

Return a new instance to handle the request or an empty reference to allow default handling of the request. the browser window that originated the request or null if the request did not originate from a browser window (for example, if the request came from CefURLRequest). frame that originated the request or null if the request did not originate from a browser window (for example, if the request came from CefURLRequest). the scheme name The request. (will not contain cookie data) Return a new instance to handle the request or an empty reference to allow default handling of the request Class representing the SSL information for a navigation entry. Returns true if the status is related to a secure SSL/TLS connection. Returns a bitmask containing any and all problems verifying the server certificate. If the certificate is valid then is returned. Returns the SSL version used for the SSL connection. Returns a bitmask containing the page security content status. Returns the X.509 certificate. SslStatus is secure cert status ssl version content status certificate Used in conjunction with CefSettings.RegisterScheme to register a scheme. You can register your own custom scheme e.g. custom:// if you are using a build in scheme (http/https) then you should directly register your using Cef.GetGlobalRequestContext().RegisterSchemeHandlerFactory - make sure the Global RequestContext has been initialized before doing so, you can use for notification of RequestContext initialization (Pass an IBrowserProcessHandler instance to Cef.Initialize) Schema Name e.g. custom Optional Domain Name. An empty value for a standard scheme will cause the factory to match all domain names. The |domain_name| value will be ignored for non-standard schemes. If true the scheme will be treated as a standard scheme. Standard schemes are subject to URL canonicalization and parsing rules as defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available at http://www.ietf.org/rfc/rfc1738.txt In particular, the syntax for standard scheme URLs must be of the form: 
              [scheme]://[username]:[password]@[host]:[port]/[url-path]
Standard scheme URLs must have a host component that is a fully qualified domain name as defined in Section 3.5 of RFC 1034 [13] and Section 2.1 of RFC 1123. These URLs will be canonicalized to "scheme://host/path" in the simplest case and "scheme://username:password@host:port/path" in the most explicit case. For example, "scheme:host/path" and "scheme:///host/path" will both be canonicalized to "scheme://host/path". The origin of a standard scheme URL is the combination of scheme, host and port (i.e., "scheme://host:port" in the most explicit case). For non-standard scheme URLs only the "scheme:" component is parsed and canonicalized. The remainder of the URL will be passed to the handler as-is. For example, "scheme:///some%20text" will remain the same. Non-standard scheme URLs cannot be used as a target for form submission. If true the scheme will be treated as local (i.e. with the same security rules as those applied to "file" URLs). Normal pages cannot link to or access local URLs. Also, by default, local URLs can only perform XMLHttpRequest calls to the same URL (origin + path) that originated the request. To allow XMLHttpRequest calls from a local URL to other URLs with the same origin set the CefSettings.file_access_from_file_urls_allowed value to true. To allow XMLHttpRequest calls from a local URL to all origins set the CefSettings.universal_access_from_file_urls_allowed value to true. If true the scheme will be treated as display-isolated. This means that pages cannot display these URLs unless they are from the same scheme. For example, pages in another origin cannot create iframes or hyperlinks to URLs with this scheme. If true the scheme will be treated with the same security rules as those applied to "https" URLs. For example, loading this scheme from other secure schemes will not trigger mixed content warnings. If true the scheme can be sent CORS requests. This value should be true in most cases where IsStandard is true. If true the scheme can bypass Content-Security-Policy(CSP) checks. This value should be false in most cases where IsStandard is true. If true the scheme can perform Fetch API requests. Factory Class that creates instances for handling scheme requests. Leave this null if you wish to manually register the scheme handler with the relevant RequestContext. Gets the underlying scheme options that represents Creates a new CefCustomScheme. Creates a new CefCustomScheme. scheme name scheme options Method used internally command line arguments list of scheme objects Interface to implement for visiting cookie values. The methods of this class will always be called on the IO thread. If there are no cookies then Visit will never be called, you must implement Dispose to handle this scenario.

Header Collection - If dealing with headers that only contain a single value then it's easier to use or . You cannot modify the referrer using headers, use . NOTE: This collection is a copy of the underlying type, to make changes, take a reference to the collection, make your changes, then reassign the collection. This example shows how to modify headers, make sure you reassign the collection once it's been modified. var headers = request.Headers; var userAgent = headers["User-Agent"]; headers["User-Agent"] = userAgent + " CefSharp"; request.Headers = headers; Post data Get the transition type for this request. Applies to requests that represent a main frame or sub-frame navigation. Gets a value indicating whether the request has been disposed of. Returns true if this object is read-only. Initialize a new instance of . Make sure to check if the is null before calling otherwise the existing data will be overridden. Returns the first header value for name or an empty string if not found. Will not return the Referer value if any.

Unlikely you'll use this yourself. the inner most instance ChromiumWebBrowser implementations implement this interface. Can be cast to the concrete implementation to access UI specific features. Event handler for receiving Javascript console messages being sent from web pages. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread.
