On every cache store, we write out to a pipe some info (url, filename, time, expire time, size, and probably some more stuff). This pipe is read by a really simple perl script that sticks this stuff in a mysql database. The actual "cache manager" is a fast-cgi script for "manual" ejections and is ran "on the command line" via cron to "prune" the cache. (it includes a small bit on Inline C.) This was done as a prototype, but works so well that we kept it. I think this was in one of my apachecon presentations. I'll try to look it up. Wish I could share source... That's a discussion I have been having here for 5 years... BTW, XFS sucked for us. It would randomly go into la-la land and nothing could be read or written. A mildly tuned ext3 seems to be good enough, although some of our caches live in /dev/shm... -- Brian Akins Chief Operations Engineer Turner Digital Media Technologies
