hello all, i have configured the isa http cache to cache all, and return any version of the object and if none exists, to return from the internet. this works out quite well as i have to make minimal calls to the internet for a lot of pages. the problem is that the pages refuse to expire in the cache. i dont mind returning only cached pages if i can return at least something that is fresh for up to 3 hours. right now, the cache is returning pages that are up to 3days old. it doesnt even try to retrieve valid pages anymore. any help on configuring the cache to expire these pages after a specified time will be appreciated. thanks in anticipation. latex.
