in reply to How should a timed session be implemented?

Not sure if this meets your needs (or is even feasible) - but what if the webpages in questions were nested in a frameset without borders, where one of the frames is only a pixel or so high and uses a metarefresh to hit a form (timer) on the server? I haven't tried this, but in theory it might work. You could then just coalate the returns and get your online hours answer.

    This works for me.

    I use a mix of hidden frames, DOM, JS and lots of perl for a "threaded" website.
    The thread frame refreshes itself every x seconds and updates a db field.
    And a cron job checks every 5 minutes, whether a user is actually online.

    So I can force logout :-)

      Could you elaborate on your cron job... I am interested in this implementation. Thanks.
        the cronjob just runs over the session/login table and calculates whether
        a given time has been overstepped.
        if that is the case, the entry/session gets deleted/terminated.

        if you want to take a look at the website
