registerSchemeHandlerFactory

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 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.
