I'm having a problem with "over cached items". I have some objects with a date field (stop publishing field). Then I have a listing that displays all the items where the date field has not already been (ie, object.date < current_date).
Problem is - when the site is cachet these items may be displayed on the listing for a day or even two past it's "stop publishing" date. How can I avoid this? Is it possible to use cronjobs to clear the cache every morning or something to that effect?
