RequestContext Class

Version 67.0.0
A request context provides request handling for a set of related browser objects. A request context is specified when creating a new browser object via the CefBrowserHost static factory methods. 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. When running in single-process mode there is only a single render process (the main process) and so all browsers created in single-process mode will share the same request context. This will be the first request context passed into a CefBrowserHost static factory method and all other request context objects will be ignored.

Properties
  NameDescription
Public propertyCachePath
Returns the cache path for this object. If empty an "incognito mode" in-memory cache is being used.
Public propertyIsGlobal
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
  NameDescription
Public methodCanSetPreference
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.
Public methodClearCertificateExceptions
Clears all certificate exceptions that were added as part of handling [!:IRequestHandler.OnCertificateError]. If you call this it is recommended that you also call [!:IRequestContext.CloseAllConnections] or you risk not being prompted again for server certificates if you reconnect quickly.
Public methodClearSchemeHandlerFactories
Clear all registered scheme handler factories.
Public methodCloseAllConnections
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().
Public methodStatic memberCreateContext
Creates a new context object that shares storage with other and uses an optional handler.
Public methodDispose
Releases all resources used by the RequestContext
Protected methodDispose(Boolean)
Releases the unmanaged resources used by the RequestContext and optionally releases the managed resources
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize (Overrides ObjectFinalize.)
Public methodGetAllPreferences
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.
Public methodGetDefaultCookieManager
Returns the default cookie manager for this object. This will be the global cookie manager if this object is the global request context. Otherwise, this will be the default cookie manager used when this request context does not receive a value via IRequestContextHandler.GetCookieManager().
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetPreference
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.
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodHasPreference
Returns true if a preference with the specified name exists. This method must be called on the CEF UI thread.
Public methodIsSame
Returns true if this object is pointing to the same context object.
Public methodIsSharingWith
Returns true if this object is sharing the same storage as the specified context.
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodPurgePluginListCache
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.
Public methodRegisterSchemeHandlerFactory
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.
Public methodResolveHostAsync
Attempts to resolve origin to a list of associated IP addresses.
Public methodResolveHostCached
Public methodSetPreference
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.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
