Do Session Attributes get GC'ed After Session Times Out?

[Mississippi John Hurt <jo...@gmail.com>]

Hi,
Say I set some HttpSession attributes. If I set the timeout to 30 minutes,
and the user leaves for lunch and never comes back for 3 days, does the
session attributes get garbage collected?  Or do I have to explicitly
invalidate the session (ie when the user comes back say 3 days later and
hits the web page again), in order for his session attributes to get
"cleaned up"?  Thanks.

The HTTP Servlet spec takes care of that.  You can even use listeners to
notify you when objects are being removed.  That way you can perform any
cleanup you require.  See:
http://tomcat.apache.org/tomcat-5.5-doc/servletapi/index.html

Specifically the HttpSessionBindingListener's description.

Regards,
David
