However, I'm not sure exactly what this means... "When the timeout was reached, the page would redirect to the logout script." Our library would like to see the following behavior after a designated time period of inactivity - search history is cleared, cart is cleared, account is logged out, and browser is redirected to the catalog home page.
An automatic logout feature (as I picture it) could clear the cart, log out the user, and redirect to the catalog home page. If by "search history is cleared" you mean the history stored in the browser, there isn't any way to do that through Koha. You'd have to use a setup like Zeno describes.
Would it be appropriate to log this as an enhancement request in Bugzilla?
