Hi Ed,
> * What affect does CacheGcInterval have on performance?
You might find it useful to split GC out into a separate process,
especially if you are sharing the cache directory over NFS.

Your filesystem performance should improve with more memory, so I would
expect mod_proxy performance to improve as a result.

You can do it with Expires headers. Make sure you send Last-Modified or
the pages won't get cached. If you don't want the rest of the world to
get your Expires headers, you'll have to modify mod_proxy to remove them.
