IRequestContext Interface
Version 55.0.0
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 [!:IWebBrowser.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.

Namespace: CefSharp

Syntax
public interface IRequestContext : IDisposable

The IRequestContext 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 CEF UI thread.
Public methodClearCertificateExceptions
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.
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 methodDispose
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
(Inherited from IDisposable.)
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 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 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.
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
Attempts to resolve origin to a list of associated IP addresses using cached data. This method must be called on the CEF IO thread. Use Cef.IOThreadTaskFactory to execute on that thread.
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.
