Typical session management works something like this:

1)  browser with no session ID connects to webserver

2)  webserver generates new session ID for client

3)  webserver "sets" session ID for client by setting a
    cookie on the client's browser that the webserver can
    use to relate the browser back to its session.

A keep-alive could be as simple as refreshing the browser window before
the timeout period elapses.
