And so, usually you have some “default rule”, when you are called by apps you dont know yet (without user agent or specific header)

I recalled how sockets work in depth a bit. You should perceive socket as 'entry' or 'end' in the tunnel. It is entry or end only from perspective of they guy who goes there, if you enter the tunel, the first hole is entry, and the last one is end, but for the guy that goes opposite direction it is opposite.


So with regards to chat service in today's system design:
- on the server side there is one listening socket, that registers the client sockets and saves them in memory. Later on they will represent connection with multiple clients.
- rooms are also our app concept, and passed with the socket message.
