Hi, folks, I want permanently cache some update packs, including Windows Update, Symantec LiveUpdate, etc. I've searched the web, and found someone using squid + apache + perl to achieve this. This is a little more complicated, and I don't think running redirectors is a good idea under heavy load. I'm here want to know, can the following lines in squid.conf do this job(not everything, almost that is ok)? refresh_pattern windowsupdate.com/.*\.(cab|exe) 4320 100% 43200 reload-into-ims refresh_pattern download.microsoft.com/.*\.(cab|exe) 4320 100% 43200 reload-into-ims refresh_pattern liveupdate.symantecliveupdate.com/.*\.zip 4320 100% 43200 reload-into-ims Thanks all. Regards, Bin
