Public classCefCustomScheme
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 ISchemeHandlerFactory using Cef.GetGlobalRequestContext().RegisterSchemeHandlerFactory - make sure the Global RequestContext has been initialized before doing so, you can use OnContextInitialized for notification of RequestContext initialization (Pass an IBrowserProcessHandler instance to Cef.Initialize)

Public interfaceIResourceHandler
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 ResourceHandler. For those upgrading, inherit from ResourceHandler instead of IResourceHandler add the override keyword to existing methods e.g. ProcessRequestAsync.
