But as I said, unless you keep details of the session in the session
database, you will not know if it is an expired session. Thus the
session database would bloat out with old crap. Yes you could have two
levels of expiry, that is, session expiry time and the session data
expiry/purge timeout, but you still could be hitting the second case.
Thus your application has to cope some how with loss of session
information anyway, so why not just deal with it.
