Not exactly. While it is possible to do some caching in a proxy like this,
the more important thing it does is buffering the content, and possibly
serving static requests for JavaScript and images. That frees up the
mod_perl processes to move on to another request. This is the same process
model used by most other systems, like FastCGI or nginx + Starman.

Yes, it goes between your load balancer and your mod_perl server.
