Client-Server: Exchange data

It depends on the protocol you use. Some need a permanent connection, some don't and some of the latter gain some speed on a permanent connection because the handshake overhead (and maybe login) is saved.
You have to decide yourself.

I have used Tcp (QTcpServer and QTcpSocket) in the problem related "here":http://developer.qt.nokia.com/forums/viewthread/6281.
My server don't receive a second request which the client sent.
