Just think of the way the HttpSession class works.
It keeps the session objects in memory (probably in a Hashtable), it maps
session objects to sessions via the session id (JSESSION), it sends the
sessionid to the user in a cookie (non-durable). It has a background,
low-priority thread that sweeps the session table looking for stale
sessions. When it finds a session it removes it, it first notifies any bound
session objects,

> In the servlet you read the session-id (request.getParmeter(....)) and get
