Kafriki does anyone have any suggestions or recommendations that they can share with me on this? Sorry, my first reply seems to have gone astray completely. re: 1) the pattern and rules you have are about as good as you can get in squid. The core design of Squid caching is to provide up-to-date copies rather than archiving stale/obsolete garbage. A better way to do this for such long times would probably be to download the data into local directories and setup your own local web server for them. Squid can be configured to fetch listed URLS from a specific cache_peer source without keeping its own duplicate copies (proxy-only option) or going to an external source (never_direct). Then you would have zero worries about loosing things out of the cache. re: 2) yes they work at the point of re-request or garbage collection (which also happens on startup/reconfigure). so retroactive on whatever is in the cache then.
