I'm attempting to setup squid as a reverse proxy, but appear to be
failing rather miserably. Whenever I attempt to get a file, I
either get a TCP_MISS/304 or TCP_MISS/200 . .I've never actually seen
a hit,
and every time I try to retrieve a file, the file gets pulled from
the webserver behind squid. I'd appreciate any help.

On the front end i'm running squid2.5-STABLE13. On the backend,
Apache 1.3.34.

Here's what I'm seeing in access.log :
