The WU requests are often Ranges though, small pieces from the middle of a file. Unless squid already has the whole file stored it has to fetch each piece separately from the web and can't yet combine them or store them. The extra settings you found (quick_abort*, range_offset, etc) should be the hack to force squid to fetch the whole object on first Range request and re-use it for the following ones WU does. > already did, I just don't know if it's working cause I don't know where > the > files are. Can you guys tell me how can I setup squid to cache the > anti-virus updates also (for kaspersky)? If the access.log shows any 304 or TCP_HIT/TCP_*_HIT messages for WU requests they are working. To do it for kaspersky if it is not already, check where the requests are going to, and why they are not being cached yet. Amos
