I have the following (high speed) Plone setup:

My problem is setting up the Virtual Host Monster rewrite rules in
Apache.
All the docs I have read assume that you are connecting straight
from Apache
to Plone (e.g. on port 8080). However, as I am using Squid as a page
cache,
something such as:
http://localhost:8080/VirtualHostBase/http/www.example.org:80/example_site/VirtualHostRoot/$1
will just bypass Squid and Pound altogether.
Am I really being dumb here and missing something obvious?
Yes :-)
Just point the rewrite to the squid port.
http://localhost:[squid_port]/VirtualHostBase/http/www.example.org:80/example_site/VirtualHostRoot/$1
assuming you have the appropriate cache_peer lines in the squid
config. If not, you may want to check into plone.recipe.squid (for
buildouts), or the "extras" download at http://plone.org/products/cachefu
(for non-buildouts), or just hand tweak your config so that it looks
something like so:
# Some basic config
visible_hostname example.com
http_port 127.0.0.1:3128 vhost defaultsite=example.com
pid_filename /path/to/squid-install/var/squid.pid
