Well in that case, can multiple squid processes share a cache directory?
I would imagine there would be problems with locks on files, etc. Could
this be solved by a master/slave relationship, or a separate program for
managing the cache? This would have other applications too, such as
several machines hooked up to a large cache via SSA, or FireWire.

I suppose that I could customize my proxy auto config file and squid.conf
file to specify something such as the following for a MP machine:

2 Processors
2 squid processes
One ip_alias entry for a card to make life pretty

squid A: .com /cache_dir_dot_com
squid B: !.com /cache_dir_other

If I remember correctly from a web page I saw, about half of proxy
traffic is directed to .com addresses.
