   if ( args == nullptr || args->Length != 2 )
   {
      Console::WriteLine( "Specify the URL to receive the request." );
      Environment::Exit( 1 );
   }

   
   HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create( args[ 1 ] ));
   request->CookieContainer = gcnew CookieContainer;
   HttpWebResponse^ response = dynamic_cast<HttpWebResponse^>(request->GetResponse());
   response->Cookies = request->CookieContainer->GetCookies( request->RequestUri );
   
   // Print the properties of each cookie.
   System::Collections::IEnumerator^ myEnum = response->Cookies->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Cookie^ cook = safe_cast<Cookie^>(myEnum->Current);
      Console::WriteLine( "Cookie:" );
