Some improvements could be made by anyone. For example, I know the main routine in perform() shall be split into several parts for readability. I apologize in advance for this kind of spaghetti code, but I was short on time to refactor it. Also chunked HTTP transfer encoding would be a nice contribution from anyone interested. It is detected but not yet supported.
