The part that uses a HttpWebRequest to download the image file resulting in a byte array containing the image. That should be isolated and unit tested. The unit test could save the byte array to a disk file that can be verified to be correct. None of that has anything to do with your "proxyServer" and sending the byte array to the client socket.

Perhaps a little planning would be helpful?" Colin Angus Mackay in the C# forum led mike
