Socket.io Session Management?

Question

Hey I was looking at socket.io and I was wondering if the socket.id persists even after a disconnect ? I am thinking it does not does anyone have any prior experience with disconnects and session management?

I was thinking of using the socket.id to be the primary key to access the user session state. Though I am worried about it not being associated with the user on a disconnect leaving a orphaned user on the server side.

Socket.io emits disconnect event after the disconnection. So when the disconnect event is triggered you can clear the session of the user.

Server

io.sockets.on('connection', function(socket) {

   socket.on('disconnect', function(data) {
      console.log('socket '+ socket.id + 'disconnected!');

      //delete the users socket here with socket.id
   });
});
