For everyone out there looking for the way to get Windows Update and Microsoft update to work through their Squid caches, here is the recipe I found to work for me. First create a text file named windowsupdate.txt in your squid configuration directory. Place these entries in it: windowsupdate.microsoft.com update.microsoft.com activex.microsoft.com download.windowsupdate.com www.download.windowsupdate.com codecs.microsoft.com stats.updates.microsoft.com c.microsoft.com Then edit your squid.conf file. Create a new acl like: acl WindowsUpdate dstdomain -i "/usr/local/etc/squid/windowsupdate.txt" Prevent caching these updates with this line: no_cache deny WindowsUpdate Make sure everyone on your squid box can get to these sites with this line: http_access allow WindowsUpdate After doing these things do a "squid -k reconfigure" Windows Update and Microsoft Update should be working just fine now through your cache, keeping your Windows boxes up to date.
