Web request works in .NET (visual studio) but not in Unity?

Question

I want to send a simple POST request to a webserver. In visual studio this flawlessly works. In Unity the server responses with 510 Not Extended. How could this be? It's just the same code.

            HttpWebRequest postRequest = (HttpWebRequest)WebRequest.Create(address);
            postRequest.CookieContainer = cookie;
            postRequest.Method = "POST";
            postRequest.KeepAlive = false;
            postRequest.ContentType = "application/x-www-form-urlencoded";
            postRequest.Accept = "text/html,application/xhtml+xml,application/xml";

            using (var writer = new StreamWriter(postRequest.GetRequestStream()))
            {
                writer.Write(parameters.ToString());
            }

Any suggestions on this?

Seems like a Mono problem to me. What .NET version are you using in VS?

I'm using .net 3.5.

My guess is that Mono implemented web requests slightly different concerning redirections (302, 303). Try disabling the AllowAutoRedirect flag to prevent the system to resend the request as a GET request.

            HttpWebRequest postRequest = (HttpWebRequest)WebRequest.Create(address);
            postRequest.CookieContainer = cookie;
            postRequest.Method = "POST";
            postRequest.KeepAlive = false;
            postRequest.ContentType = "application/x-www-form-urlencoded";
            postRequest.Accept = "text/html,application/xhtml+xml,application/xml";
            postRequest.AllowAutoRedirect = false;

I guess it's a webserver problem. Try disabling redirection on the server.
