Autologout implementation

Rate this Message:
How would you implement automatic logout after a given period of
inactivity? The app is running in a workshop, where a bunch of people use the same machine to access their scheduled tasks and other stuff. They will often leave "their" last page on the screen, so the goal donor requested an automated reload of the starting page. I did this for another app (in IOWA on Ruby) by meta-refreshing to the "/logout" page, which in turn expired the session and redirected to the starting page. Below is what I came up with in Seaside. This decoration is autmatically added to the pages if the users are in the autologout category. Has anybody a better idea for this? Thanks, s.

Instead of manually expiring it, yes. This could happen after authentication on a per-user basis. But I still need the reload of the start page so that the machine appears "free". hmm... I need to try what happens when I set the session timeout to 120s and refresh after 125s.
