Hi list, I am testing a slightly modified version of the chat_client/chat_server ASIO examples and I have noticed that, immediately after the tcp::socket::async_connect() call from inside the chat_client constructor, the client is creating and establishing not one, but three TCP connections, only one of which is targeting to the server-port. Furthermore, calling repeatedly the async_connect() seems to constantly create three connections per call. I have also noticed that other programs in my system, which also communicate via TCP (ie the hyper-terminal), only open one connection at the client side. Is this async_connect() behavior, which I have mentioned above, the expected/natural behavior, or maybe I am doing something wrong? If this behavior is expected, is there a reason for it? Do I have a choice to change it? Please note that there is a near-4000 outbound concurrent connections default limit in many Windows-XP installations, hence this question has a practical meaning.
