Squid deployed as a reverse proxy routinely handles 800 requests/second on any decent hardware (I think I've seen reports floating around speaking of 2000). > Has anybody else here migrated from using Apache's mod_cache to Squid, and > if so do you have any insights? > > Lastly, if I do decide to use Squid, is the O'Reilly book from 2004 still > relevant, or is it out of date now?

You can use that as a basic guide, and then refer to the wiki ( http://wiki.squid-cache.org/ ) to drill into specific details. For any doubts, just ask on the squid-users mailing-list. -- /kinkie
