We're using Squid as a Web accelerator and need to clear the cache every morning (the store goes into maintenance mode at 4 a.m. and all pages have a message saying so; we don't want those pages cached). Based on FAQ 7.3 (http://www.squid-cache.org/Doc/FAQ/FAQ-7.html#ss7.3), I wrote this script to clear my Squid cache: /usr/local/squid2/sbin/squid -k shutdown echo "" > /cache/swap.state /etc/init.d/squid start This works but it sometimes has problems. Most of the times I've run it, it works great. However, sometimes when I run it, it says there are no running instances of Squid, and then subsequently Squid doesn't start up. Any ideas on why this might be? I have been running the script a few times in a row, which might be part of the problem ... could it just be that I'm not giving it enough time before running it again, or could something else be at work? Also, does anyone have suggestions on causing a certain set of URLs to not be cached during a certain time of night? My idea right now is to have two squid.conf files -- one that includes the URLs affected by maintenance mode and one that doesn't include them -- and setting up cron jobs to switch between config files before and after the maintenance period. Thanks! Jen
