  I'm using the syntax to load them from an external text file:

acl lava_domains dstdomain "/usr/local/etc/squid/lavadomains"

  along with the following (relevant portions excerpted)...

acl lava_dests dst x.y.z.0/255.255.252.0
acl lava_dests dst x.w.v.0/255.255.248.0
...

no_cache deny lava_dests
no_cache deny lava_domains
always_direct allow lava_dests
always_direct allow lava_domains

  lavadomains is nearly 800 lines, so I'm sure I'm taking a big
performance hit on that. However, if I don't use the domain ACL, I'm
concerned about the possibility of sporadically getting pages for a
customer web site put into the cache. In that case, Murphy's Law says
that customer will then update their site and flip out when they don't
see it reflected in their browser immediately, due to the cache serving
the stale pages.
