OK. So far AFAIU from RFC2616, the algorithm is as follows: If the request headers contains "TE: chunked" we understand that the client supports chunked encoding. According to the RFC, to be HTTP/1.1 compliant, servers MUST support this feature. Clients SHOULD.
Server replies with Transfer-Encoding: chunked in the response hader and NO content-length. Then it before sends the first packet, it sends the hexadecimal length of the packet: <response header>\r\n <sizeinHEX>\r\n <packet/data>\r\n <sizeinHEX>\r\n <packet/data>\r\n ... 0\r\n (until the server says 0 length) I will implement this feature in C++ next week and then post the code here so that you take a look, provide feedback and then translate to Delphi.
