Re: [ProgSoc] Detecting JSP session timeouts

[Bryn Price <redshift@nospam.progsoc.uts.edu.au>]

Jay,
Please excuse this email cause i'm at the end of a very long week, but
could you not use getSession(false) and check if the session is null then
create a new one if it is needed? I'm not sure who is managing the
creation of Sessions, but i use this technique to do a similar thing to
you.

Cheers,
Bryn
