Description (last modified by osimons)

I have install XmlRpcPlugin and HttpAuthPlugin, I am not sure, where exactly is the error. when I connect by my .NET client to the XmlRpc, I get this exception from request.GetResponse() (.NET method)

I debugged it by fiddler HTTP debugger and I have found, that trac send wrong Content-Length (23bytes). It sends text "Authentication required" which is exactly 23bytes. But there is small HTML block appended, which cause, that content length is wrong. I can reproduce it with python 2.5 and python 2.7 as well. I have attached the output of fiddler, please see bellow. I find interesting, that the request is made via HTTP 1.1, but in repsonse HTTP 0.9 is mentioned.

XmlRpcPlugin is not involved in authentication at all, so moving it to that other plugin.
