      // Sends the HttpWebRequest and waits for a response.
      HttpWebResponse^ myHttpWebResponse = dynamic_cast<HttpWebResponse^>(myHttpWebRequest->GetResponse());
      if ( myHttpWebResponse->StatusCode == HttpStatusCode::OK )
      {
         Console::WriteLine( "\r\nResponse Status Code is OK and StatusDescription is: {0}",
            myHttpWebResponse->StatusDescription );
      }
      // Releases the resources of the response.
      myHttpWebResponse->Close();
   }
   catch ( WebException^ e ) 
   {
      Console::WriteLine( "\r\nWebException Raised. The following error occurred : {0}", e->Status );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "\nThe following Exception was raised : {0}", e->Message );
   }
}

            // Creates an HttpWebRequest for the specified URL.
            HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
            // Sends the HttpWebRequest and waits for a response.
            HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
            if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
               Console.WriteLine("\r\nResponse Status Code is OK and StatusDescription is: {0}",
                                    myHttpWebResponse.StatusDescription);

        }
    catch(WebException e)
