Windows Phone 7.5 POST method return remote server not found

Question

I'm trying to make a POST but every time returns an error saying

"The remote server returned an error: NotFound."

I'm using Firebug extension of Firefox to get all the necessary parameters of the POST method but firebug says

"... Firebug request size limit has been reached by Firebug. ..."

. Also wireshark says more or less the same thing.

I don't know if I need to specify (on windows phone 7 HttpWebRequest) some extra parameters on header because of the long POST method.

This is my code:

private void GetResponseCallbackAGCP(IAsyncResult asynchronousResult)
{
  Uri url = new Uri("http://publico.agcp.ipleiria.pt/Paginas/ScheduleRptCursosSemanalPublico.aspx");
 postData = "MSO_PageHashCode=" + _MSO_PageHashCode +

                "&__spDummyText1=__spDummyText1&__spDummyText2=__spDummyText2";

            cc = new CookieContainer();

            webRequest2 = (HttpWebRequest)WebRequest.Create(url);
            webRequest2.Method = "POST";
            webRequest2.ContentType = "application/x-www-form-urlencoded";
            webRequest2.CookieContainer = cc;

            webRequest2.BeginGetRequestStream(new AsyncCallback(GetRequestCallback), webRequest2);
}


   private void GetRequestCallback(IAsyncResult asynchronousResult)
        {
            var request = asynchronousResult.AsyncState as HttpWebRequest;
            StreamWriter stream = new StreamWriter(request.EndGetRequestStream(asynchronousResult));
            stream.Write(postData);
            stream.Flush();
            stream.Close();
            request.BeginGetResponse(AuthCallback, request);
        }

        private void AuthCallback(IAsyncResult asyncResult)
        {
            HttpWebRequest request = (HttpWebRequest)asyncResult.AsyncState;
            HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asyncResult); //RETURNS an error saying "WebException was unhandle. The remote server returned an error: NotFound."
            using (StreamReader streamReader1 = new StreamReader(response.GetResponseStream()))
            {
                //string resultString = streamReader1.ReadToEnd();
                var info = streamReader1.ReadToEnd();
                System.Windows.Deployment.Current.Dispatcher.BeginInvoke(() =>
                {
                    webView.NavigateToString(info);
                });

            }
        }

Thanks in advance!

Try using RestSharp, it greatly simplifies the Http stuff. I have been using RestSharp in all my WP7 Projects.
