Request |
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
RequestContext 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.

SyntaxThe RequestContext type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RequestContext | Initializes a new instance of the Object class. |
| RequestContext(IRequestContext) | Initializes a new instance of the RequestContext class |
| RequestContext(IRequestContextHandler) | Initializes a new instance of the RequestContext class |
| RequestContext(RequestContextSettings) | Initializes a new instance of the RequestContext class |
| RequestContext(IRequestContext, IRequestContextHandler) | Initializes a new instance of the RequestContext class |
| RequestContext(RequestContextSettings, IRequestContextHandler) | Initializes a new instance of the RequestContext class |
Properties| Name | Description | |
|---|---|---|
 | CachePath | Returns the cache path for this object. If empty an "incognito mode" in-memory cache is being used. |
| IsDisposed | Gets a value indicating whether the RequestContext has been disposed of. |
| IsGlobal | 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. |
Methods| Name | Description | |
|---|---|---|
| CanSetPreference | 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. |
| ClearCertificateExceptions | Clears all certificate exceptions that were added as part of handling OnCertificateError(IWebBrowser, IBrowser, CefErrorCode, String, ISslInfo, IRequestCallback). If you call this it is recommended that you also call CloseAllConnections(ICompletionCallback) or you risk not being prompted again for server certificates if you reconnect quickly. |
| ClearHttpAuthCredentials | Clears all HTTP authentication credentials that were added as part of handling GetAuthCredentials(IWebBrowser, IBrowser, String, Boolean, String, Int32, String, String, IAuthCallback). |
| ClearSchemeHandlerFactories | Clear all registered scheme handler factories. |
| CloseAllConnections | 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(). |
 | Configure | Creates a new RequestContextBuilder which can be used to fluently set preferences |
| Dispose | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetAllPreferences | 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. |
| GetCookieManager | Returns the default cookie manager for this object. This will be the global cookie manager if this object is the global request context. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetPreference | 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. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| HasPreference | Returns true if a preference with the specified name exists. This method must be called on the CEF UI thread. |
| IsSame | Returns true if this object is pointing to the same context object. |
| IsSharingWith | Returns true if this object is sharing the same storage as the specified context. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| RegisterSchemeHandlerFactory | 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. |
| ResolveHostAsync | Attempts to resolve origin to a list of associated IP addresses. |
| SetPreference | 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. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
| UnWrap | Used internally to get the underlying IRequestContext instance. Unlikely you'll use this yourself. |
Extension Methods| Name | Description | |
|---|---|---|
 | ClearHttpAuthCredentialsAsync |
Clears all HTTP authentication credentials that were added as part of handling
GetAuthCredentials(IWebBrowser, IBrowser, String, Boolean, String, Int32, String, String, IAuthCallback).
(Defined by RequestContextExtensions) |
| GetCookieManagerAsync |
Gets the cookie manager associated with the IRequestContext. Once the cookie manager
storage has been initialized the method will return.
(Defined by RequestContextExtensions) |
| RegisterOwinSchemeHandlerFactory |
Extension method to register a instance of the OwinSchemeHandlerFactory with the provided appFunc
for the domainName (Defined by RequestContextExtensions) |
| SetPreferenceAsync |
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.
