+Summary: Web client redirect fails when using proxy on web request
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+When making an http web request to an http web server, the web request 
+fails if the request is redirected (302) and the request was sent via a 
+proxy.
+
+Steps to reproduce the problem:
+1. Run the code below. The hard coded address in the WebRequest is valid 
+and you can use it to reproduce the problem.
+2. Set up an HTTP web proxy (Apache or Squid is easy) and change the 
+WebProxy constructor to point at your web proxy.
+3. Run the code.
+
+using System;
+using System.Net;
+using System.Web;
+
+namespace Test
+{
+	/// <summary>
+	/// Summary description for Test.
+	/// </summary>
+	public class Test
+	{
+		/// <summary>
+		/// The main entry point for the application.
+		/// </summary>
+		[STAThread]
+		static void Main(string[] args)
+		{
+			CertPolicy cp = new CertPolicy();
+
+			HttpWebRequest webRequest = (HttpWebRequest)
+WebRequest.Create( "https://193.97.125.1/simias10/DomainService.asmx" );
+			webRequest.Proxy = new WebProxy
+( "http://137.65.56.81:8080" );
+			try
+			{
+				HttpWebResponse response = 
+webRequest.GetResponse() as HttpWebResponse;
+				Console.WriteLine( "Redirected url = 
+{0}", response.ResponseUri );
+			}
+			catch( WebException ex )
+			{
+				Console.WriteLine( "Web exception {0}", 
+ex.Message );
+				HttpWebResponse exResponse = ex.Response 
+as HttpWebResponse;
+				if ( exResponse.StatusCode == 
+HttpStatusCode.Unauthorized )
+				{
+					Console.WriteLine( "Redirected 
+url = {0}", exResponse.ResponseUri );
+				}
+			}
+		}
+	}
+}
+
+
+Actual Results:
+Receives a WebException: SendFailure with a nested exception of 
+NullReferenceException.
+
+Expected Results:
+Expect to get the redirected URI.
+
+
+How often does this happen? 
+Every time if the proxy is specified in the WebRequest. If the proxy is 
+removed from the WebRequest, it completes successfully.
+
