This is a transparent cache for Debian and RedHat packages (.deb and .rpm). It is based on apt-cacher available on Debian. It has been enhanced to handle RedHat repositories and files whose names are the same but the contents are different.
It would seem that pkg-cacher is not actually caching a lot of the time. From my access.log:

So there was one HIT, 1 day after a MISS but much longer than 1 day and the same file does not remain cached.
But also, the last two MISSes as you can see, were not very far apart either.
