Since you can't really push with http, how about setting a flag that tells
your servlet to only serve your "The service is going down in xx minutes.
Please log off" page with a nice big logoff button. Once all the sessions
have been invalidated, you can shut down immediately, otherwise after some
time period had expired I'd assume the sessions were stale and shut down
anyway.
