Question

I am connecting to a service using a HttpWebRequest. In the service logs, there are Authentication errors being logged, even though the information is correct. The vendor who set up the server with the service, has said that .NET does not send the authentication headers on the first try.

_Req.Credentials = new NetworkCredential(username, password); 

When the request is sent, the server responds with needing the headers, which the request then sends. Is this correct, and is there a way to send it on the initial request?

Answer 1

HttpWebRequest request; request.PreAuthenticate = true;
