Create A Multipart Form-data Response

[aalbetski]

I need to create an HttpWebResponse usin multipart/form-data. This is what I have so far: StringBuilder sb = new StringBuilder(); sb.Append("--xyz\r\n"); sb.Append("Content-Disposition: form-data; name=\"PayloadType\"\r\n\r\nX12_270_004010X092A1\r\n"); sb.Append("--xyz\r\n"); sb.Append("Content-Disposition: form-data; name=\"ProcessingMode\"\r\n\r\nRealTime\r\n"); sb.Append("--xyz--"); byte[] Postdata = System.Text.Encoding.Default.GetBytes(sb.ToString()); Response.AddHeader("Content-Type", "multipart/form-data; boundary=xyz"); Response.AddHeader("Content-Length", Postdata.Length.ToString()); Response.AddHeader("Content-Encoding", "multipart/form-data"); Response.OutputStream.Write(Postdata, 0, Postdata.Length); Response.End();It just doesn't seem to work. Is the output stream supposed to be part of the header? When I call this from a client, all parts of the response are output to the page. I'm new to multipart and would appreciate any insights
