[Mono-list] HttpWebRequest HTTPS problem - WebExceptionStatus.SendFailure

[Timothy Parez]

Hi,

Someone pointed me to this document:
http://www.mono-project.com/UsingTrustedRootsRespectfully


But when I use something similar to the code on that page just to test:
catch (WebException we) {
			if (we.Status != WebExceptionStatus.TrustFailure)
				throw;
			Console.WriteLine ("You do not trust the people who " +
				"issued the certificate being used by '{0}'." +
				" Please see the application help file on " +
				"the 'trust certificate' subject to learn " +
				"about how this can be fixed.", args [0]);

It simply throws this again:

error writing request.

Description: Error processing request.

Error Message: HTTP 500. System.Net.WebException: Error writing request.

Stack Trace:

System.Net.WebException: Error writing request.
   at System.Net.WebConnectionStream.WriteRequest () [0x00169] in /usr/ 
src/mono-1.2.6/mcs/class/System/System.Net/WebConnectionStream.cs:563
   at System.Net.WebConnectionStream.Close () [0x000e0] in /usr/src/ 
mono-1.2.6/mcs/class/System/System.Net/WebConnectionStream.cs:613
   at GoogleDocumentManager.Authenticate () [0x000b5] in /tmp/www-data- 
temp-aspnet-0/b9f31472/70040e1b._4.cs:279

The actual status is WebExceptionStatus.SendFailure.

Any ideas?
