Hi All,

I have a standalone application having a form, which will be prompting for username, password and the name (IP) of the server to connect to. On entering the details, it should connect to that particular server (Windows server) and should be able to upload the required files to a physical folder in the windows server. But HttpWebRequest.GetResponse on POST returns 405 method not allowed error. Any help is appreciated.

Thanks in advance

Below is the code snippet

private void Login(string UID, string PWD)
        {
            string strreq = WriteLoginReqXML(UID, PWD);
            string ct = "http://" + comboBox1.Text;            
            string ct1 = comboBox1.Text;
            Uri ur = new Uri(ct);
            UriBuilder MSPage = new UriBuilder();
            MSPage.Scheme = "http";
            MSPage.Host = ct1;
            MSPage.Port = 80;
            Uri CompletedUri = MSPage.Uri;
            HttpWebRequest request =         (HttpWebRequest)WebRequest.Create(CompletedUri);
            String windowsAuthType = "Basic";

            CredentialCache cache = new CredentialCache();
            cache.Add(ur,windowsAuthType,new NetworkCredential(UID,PWD));
            request.ContentType = "application/x-www-form-urlencoded";

            request.Credentials = cache;
            request.PreAuthenticate = true;
            request.Method = "POST";
         
            request.ContentType = "application/x-www-form-urlencoded";

            string strBuffer = "Ghi";

            byte[] buffer = Encoding.ASCII.GetBytes(strBuffer);

            request.ContentLength = buffer.Length;

            Stream PostData = request.GetRequestStream();

            PostData.Write(buffer, 0, buffer.Length); 

            PostData.Close();

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                if (response.StatusCode != HttpStatusCode.OK)
                    MessageBox.Show("OK");
