CefRequestContext Class

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 via the CefBrowserHost static factory methods or when creating a new URL request via the CefURLRequest 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.

public sealed class CefRequestContext : IDisposable

The CefRequestContext type exposes the following members.

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 browser process UI thread.
Public methodClearCertificateExceptions Clears all certificate exceptions that were added as part of handling CefRequestHandler::OnCertificateError(). If you call this it is recommended that you also call CloseAllConnections() or you risk not being prompted again for server certificates if you reconnect quickly. If |callback| is non-NULL it will be executed on the UI thread after completion.
Public methodClearSchemeHandlerFactories Clear all registered scheme handler factories. Returns false on error. This function may be called on any thread in the browser process.
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 CefShutdown(). If |callback| is non-NULL it will be executed on the UI thread after completion.
Public methodStatic memberCreateContext(CefRequestContext, CefRequestContextHandler) Creates a new context object that shares storage with |other| and uses an optional |handler|.
Public methodStatic memberCreateContext(CefRequestContextSettings, CefRequestContextHandler) Creates a new context object with the specified |settings| and optional |handler|.
Public methodDisposeReleases all resources used by the CefRequestContext
Public methodEqualsDetermines whether the specified object is equal to the current object.

Protected methodFinalize
(Overrides ObjectFinalize)
Public methodGetAllPreferences Returns all preferences as a dictionary. If |include_defaults| is true then preferences currently at their default value will be included. 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 CefRequestContextHandler::GetCookieManager(). If |callback| is non-NULL it will be executed asnychronously on the IO thread after the manager's storage has been initialized.
Public methodStatic memberGetGlobalContext Returns the global context object.
Public methodGetHandler Returns the handler for this context if any.
Public methodGetHashCodeServes 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 browser process UI thread.
Public methodGetTypeGets 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 browser process UI thread.
Public methodIsSame Returns true if this object is pointing to the same context as |that| object.
Public methodIsSharingWith Returns true if this object is sharing the same storage as |that| object.
Public methodPurgePluginListCache Tells all renderer processes associated with this context to throw away their plugin list cache. If |reload_pages| is true they will also reload all pages with plugins. CefRequestContextHandler::OnBeforePluginLoad may be called to rebuild the plugin list cache.
Public methodRegisterSchemeHandlerFactory Register a scheme handler factory for the specified |scheme_name| and optional |domain_name|. An empty |domain_name| 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 |scheme_name| is a built-in scheme and no handler is returned by |factory| then the built-in scheme handler factory will be called. If |scheme_name| 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 |scheme_name| and optional |domain_name|. Returns false if an error occurs. This function may be called on any thread in the browser process.
Public methodResolveHost Attempts to resolve |origin| to a list of associated IP addresses. |callback| will be executed on the UI thread after completion.
Public methodResolveHostCached Attempts to resolve |origin| to a list of associated IP addresses using cached data. |resolved_ips| will be populated with the list of resolved IP addresses or empty if no cached data is available. Returns ERR_NONE on success. This method must be called on the browser process IO thread.
Public methodSetPreference Set the |value| associated with preference |name|. Returns true if the value is set successfully and false otherwise. 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 browser process UI thread.
Public methodToStringReturns a string that represents the current object.
