There is always a default session expiry time. This can be overridden by the
servlet. There is no way by which the session can be invalidated if the
browser
is closed. This is not possible using html and servlets alone.
If you want to continuously monitor the user, you have to use an applet
which
"pings" the server at regular intervals or some complex JavaScript and
frames.
The best solution is the simplest solution (for us programmers!). Put as
much
resources as possible into the server and don't worry about session expiry
etc.
or maybe you can implement your own session handling logic using cookies and
a database like oracle. In this case, you can dedicate a set of boxes for
session management alone and can be isolated from the web server.
Is there any third party tool which takes care of these? It would be great
and
save lots of time and effort.
