Hello! I wanna develop a Http client program! I use three classes (CInternetSession, ChttpConnection, Chttpfile) for doing this! Now I can connect to my web LAN server, send request, and get the response. However, when it finished, I use functions Chttpfile::Close() ChttpConnection::Close(), and CInternetSession::Close() to disconnect to the server. But It doesn't work at all. I also "delete" theses three classes. But the connection still exists until the server disconnect this connection, or I shutdown the program. Is there any solution to disconnect it? Thank you very much!
