Alright, that did the trick. The only other problem I ran into is
that the $request_filename variable is an absolute path. I had been
trying to use that variable in a path like $document_root/cache/
$request_filename.html - this didn't work, I had to use the $uri
variable instead: $document_root/cache/$uri.html
Thanks again!
