Continuous sessions

[fscherf]

I am trying to use aiohttp-sockjs in my web framework Lona and have some questions regarding session management.

SockJS timeouts: SockJS does not hold onto one websocket connection at a time but regularly closes and reopens them. Why is that? Is this that a way to prevent the browser close the connection because of inactivity?

SockJS client identification: SockJS uses multiple connections and requests for one continuous session, but there seems to be no session identifier, known to the server and the client (or i missed it when I read the code). Is there a way to identify and distinct clients and browser tabs or should that be part of the application code?
