Well, this is not difficult to do :) - because you do TCP connection re-usage and avoid opening and searching for TCP conns. I think the question is not from technical point of view, but more a logical one. Like known issues not to do TCP ping; does TCP ping may help after all? how TCP ping and TCP keepalive work?
