I have read what . . . reload-into-ims . . . is supposed to mean here: http://www.squid-cache.org/Versions/v3/3.1/cfgman/refresh_pattern.html <http://www.squid-cache.org/Versions/v3/3.1/cfgman/refresh_pattern.html> Basically this is all that it says: (QUOTE) reload-into-ims changes client no-cache or ``reload'' to If-Modified-Since requests. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. (END QUOTE) I am trying to understand what it is doing with respect to the FAQ's tips on code to add to your squid.conf file that will help cache Windows Updates. That code is given here: http://wiki.squid-cache.org/SquidFaq/WindowsUpdate <http://wiki.squid-cache.org/SquidFaq/WindowsUpdate> . . . and a sample of one of the refresh_pattern lines from that page is this: refresh_pattern -i microsoft.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-ims *Question 1:* Could someone please clarify what the system is going to be 'thinking' with this code? *Question 2:* My understanding of windows updates is that '/An update, is an Update/'. Why would I set a limit on a cached update to 30 days (43200)? Why would I not make that number equivalent to 3 or 4 years (or more); is each windows update that you download not its own entity, never to be changed - /except to be updated by a future update/? Thanks for the assistance in leaning. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/refresh-pattern-AND-reload-into-ims-tp4661704.html Sent from the Squid - Users mailing list archive at Nabble.com.
