I've been trying to setup apache to do memory caching of my static files, I
run 4 servers serving only .js and .css files as well as some images. this
machines have 2 gigs of ram and only run apache. I've been able to use the
file cache without a problem and can see it caches them in the error log
with level debug but when i enable it for memory it will always re request
the file even though it says it cached the url
Here is some info

Disk cache works perfectly for when i want to cache output of dynamic pages
but for static files it would be great if i could just spit them out from
memory. I have tried making the size of the cache bigger in memory to 1 gig
still same issue.
