Hi, As a rule squid works pretty well, except that it seems to 'loose' objects from the cache when the machine is restarted and or after a few hours/days. It then re-downloads files that have not changed. All I need is a simple setup that will cache as much as possible (use as much of the cache size as possible) and only download files when they've changed. I do lots of Linux re-installs inside VMs and I'd like to source updates from the cache instead of downloading the same RPMs over and over again. Could someone perhaps tell me what I need to change in my conf file?
