I'm new to the list (and the configuration I'm trying to pull off
below), so take it easy on this noob :-)

I'm trying to protect a pretty fragile tomcat server by setting up
apache httpd in front of it.

I've set up a proxy/proxy pass and can see the contents served up
properly.

Ok  -  so step 2 - I'm trying to turn on caching and have a few
questions.

If a requested url I'd like to cache is something like:

http://server/foo/<somerandomdirname>/directory/this

And I only want to cache things in directory/this and/or deeper, how
can I do this?

I've been only able to cache things using:

CacheEnable disk / #Cache everything - don't want to do this
CacheEnable disk /foo #Cache everything under foo - still don't want
to do this
CacheEnable disk directory/this #Cache anything that comes through
ending with a "directory/this" - doesn't work for obvious reasons.
CacheEnable disk /foo/<instanceofrandomdirname>/directory/this #Cache
this particular instance of this thing, but there are sometimes
hundreds of these directories. so this isn't possible either.

What I'm getting at is, is it possible to do some kind of wildcard
entry in the url parameter?

Something like this:

CacheEnable disk /foo/*/directory/this

?
