For those of you scouring the web looking for a simple routine that sends/receives an XML file using HttpWebRequest/Response here ya go:

            objHttpWebRequest.ContentType = "text/xml; encoding='utf-8'";

            //Get Stream object 
            objRequestStream = objHttpWebRequest.GetRequestStream();

            //Writes a sequence of bytes to the current stream 
            objRequestStream.Write(bytes, 0, bytes.Length);

            //Close stream
            objRequestStream.Close();

            //---------- End HttpRequest

            //Sends the HttpWebRequest, and waits for a response.
            objHttpWebResponse = (HttpWebResponse)objHttpWebRequest.GetResponse();

            //---------- Start HttpResponse
            if (objHttpWebResponse.StatusCode == HttpStatusCode.OK)
            {
                //Get response stream 
                objResponseStream = objHttpWebResponse.GetResponseStream();
