HTTPWebRequest PUT/POST Error : Method not allowed

Hi ,

I'm trying to upload a file to a remote server using HTTPWebRequest (both PUT and POST) (We are using asp.net 1.1, there's no FTPWebrequest in 1.1 and Webclient doesn't work either). But when I run the code, it gives me this error:

The remote server returned an error: (405) Method Not Allowed

Below is the code I'm using. Please let me know what am I doing wrong here.

 try
            {
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(@"http://FolderPathASURL/");
                req.Credentials = new NetworkCredential(@"username", "password");
                req.Method = "PUT"; //Tried POST as well
                req.AllowWriteStreamBuffering = true;
                // Retrieve request stream
                Stream reqStream = req.GetRequestStream();
                // Open the local file
                FileStream rdr = new FileStream(@"C:\TestFile.txt", FileMode.Open);
                // Allocate byte buffer to hold file contents
                byte[] inData = new byte[4096];

                // loop through the local file reading each data block
                //  and writing to the request stream buffer
                int bytesRead = rdr.Read(inData, 0, inData.Length);
                while (bytesRead > 0)
                {
                    reqStream.Write(inData, 0, bytesRead);
                    bytesRead = rdr.Read(inData, 0, inData.Length);
                }

                rdr.Close();
                reqStream.Close();
                req.GetResponse();
            }
            catch (System.Net.WebException we)
            {
                Console.WriteLine(we.Message);

                if (we.Status == WebExceptionStatus.ProtocolError)
                    Console.WriteLine(we.Response.ResponseUri);
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                Console.ReadLine();
            }
