Depends on how cache aware the web site was. If the web site did this correctly in a planned manner they set the expiry date on the old content to shortly before they planned on doing the update. Most don't and in such case Squid guesses how often the content is updated based on how old it is. See refresh_pattern. > Is there an ageing process? Yes. Regards Henrik
