+Summary: Missing WebException.Response property.
+
+When a call to HttpWebRequest.GetResponse() results in a WebException
+being thrown, the Response property of this exception is NULL when,
+in .NET, it is set to an instance of HttpWebResponse.
+
+This means that it is not possible to determine the HTTP status code
+returned in MONO (this is indicated by the StatusCode property of the
+nonexistent HttpWebResponse object).
+
+This is new behaviour in Release 0.24... HttpWebResponse.GetResponse()
+never used to throw a WebException at all, but this was changed to improve
+consistency with .NET.
+
+
+Steps to reproduce the problem:
+1. Please see sample program
+
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: A null value was found
+where an object instance was required
+in <0x00116> 00 .HttpTest:Main (string[])
+
+(Output obtained by running the sample program in MONO 0.24).
+
+
+Expected Results:
+Server returned error: NotFound
+
+(Output obtained by running the sample program in .NET).
+
+
+How often does this happen?
+Always in MONO, never in .NET.
+
+
+Additional Information:
+
+-----Sample program starts here-----
+using System;
+using System.Net;
+
+public class HttpTest
+{
+ public static void Main(string[] args)
+ {
+ try
+ {
+ HttpWebRequest httpreq = (HttpWebRequest)
+WebRequest.Create("http://www.go-mono.com/not-here.html");
+ HttpWebResponse httpresp = (HttpWebResponse)
+httpreq.GetResponse();
+
+ // Expect WebException to be thrown by now.
+
+ Console.Out.WriteLine("Eh?... This page shouldn't
+exist!");
+ }
+ catch (WebException e)
+ {
+ // Something went wrong! So what's the status code?
+ HttpWebResponse badresp = (HttpWebResponse)
+e.Response;
+ Console.Out.WriteLine("Server returned error: " +
+badresp.StatusCode); // Exception is thrown here, because e.Response is
+null (at least it is in MONO).
+ }
+ }
+}
+-----Sample program ends here-----
