        static void RequestMutualAuth(Uri* resource)
            // Create a new HttpWebRequest object for the specified resource.
            WebRequest* request=dynamic_cast<WebRequest*> (WebRequest::Create(resource));
            // Request mutual authentication.
           request->AuthenticationLevel = AuthenticationLevel::MutualAuthRequested;
            // Supply client credentials.
            request->Credentials = CredentialCache::DefaultCredentials;
            HttpWebResponse* response = dynamic_cast<HttpWebResponse*> (request->GetResponse());
            // Determine whether mutual authentication was used.
            Console::WriteLine(S"Is mutually authenticated? {0}", __box(response->IsMutuallyAuthenticated));
            // Read and display the response.
            Stream* streamResponse = response->GetResponseStream();
            StreamReader* streamRead = new StreamReader(streamResponse);
            String* responseString = streamRead->ReadToEnd();
            // Close the stream objects.
            // Release the HttpWebResponse.
