				HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
				Console.WriteLine("\nThe server did not issue any challenge.  Please try again with a protected resource URL.");
				// Releases the resources of the response.
		catch(WebException e) 
			    HttpWebResponse response = (HttpWebResponse)e.Response;
				if (response != null)
					if (response.StatusCode == HttpStatusCode.Unauthorized)
