Hello again Helumt, I have been playing with the wsusoffline, & learning more about it. What I have discovered is that it only will bring a system up to a 'patched' level - critical security updates only. Important updates are not included. It is STILL a vast improvement over what I have done in the past (download EVERYTHING - EVERY TIME). So for what it is worth, some how being able to incorporate a WU cache/store would be very helpful. I know caching is not a great option due to the overwriting issues. My solution is to use a 'Large' Cache, and to use the *cache_replacement_policy heap LFUDA* Hopefully this will help keep whatever Squid can get it's hands on in the cache as long as possible. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Any-Way-To-Check-If-Windows-Updates-Are-Cached-tp4661935p4662033.html Sent from the Squid - Users mailing list archive at Nabble.com.
