Poor answer but the best I can give you. > Yikes... Running multiple Squid processes sharing the same cache_dir is just asking for trouble. Each instance will assume that it has the directory to itself, and will not inform other instances when it adds or removes files. Each instance will also assume that it has however much space assigned to that cache dir; three processes will use three times as much space as you might expect with this setup.
In any case, one Squid instance should be capable of doing what you are asking for: http://www.squid-cache.org/mail-archive/squid-users/200010/0704.html
