.50 is a squid server (which, incidentally, forwards to .12 and .11).
Zips can tie up an apache child for a long time. Better still, those
download managers that open some 20 connections at once can tie up many
children for a long time. Squid handles that much better.

We plan to upgrade to beefier front line servers (they're Celeron/366s
with 8GB drives right now) that can actually cache the large files we need
the zipcache for now.

No reason. Squid will never actually reach the httpd_accel server. It's
just there to put squid in httpd-accel mode.

Again, I'm not sure how much it matters, since squid will never handle
requests through this path.

This means squid will return an error if you upload more than 3MB. Squid
does not cache POST requests. You may want to set this to 0kb (unlimited).

You can probably hack the squid log to include cookies (or you can log all
headers, but that gets really big) if you need to track who accesses which
images. We don't have any need for that, so we don't track users on
static files.
