For servlet engines based on the 2.0 API, whether or not you can control the
lifetime of the session id cookie is specific to each servlet engine. Look in
the configuration parameter options for your engine for something that lets
you set the "cookie timeout" or some such name.
In servlet engines based on the 2.1 API, you can set the timeout yourself, on
a per-session basis, with HttpSession.setMaxInactiveInterval(). What you are
setting is the number of seconds that the servlet engine will wait for another
access, before invalidating the session -- the absolute expiration time is
updated each time the cookie is sent. As a side effect, though, the cookie
will be stored on the client side.
