If I understood you correctly, you should look into WebSockets. Making AJAX calls to server for an update is a bad idea because if multiple people keep making AJAX calls for updates, it will take up all of your resources. I personally run NodeJS WebSocket server (socket.io) and make all communication via that server. This allows user to QUICKLY send information and for server to notify ALL connected users about those changes. Couple of tutorials for Socket.io : [this video] [LINK] [LINK]

What I want is to be able to detect the specific user who logged out. By logging out, I mean closing the window (as I have not incorporated any logging in or logging out with actual credentials such as username or password).
