[squid-users] Large Files Not Caching

[Benjamin Reed]

I'm trying to set up a CDN-like frontend to our (bandwidth-constrained)
master package repository.  Everything seems to be working (including
memory cache hits) except for some reason it does not seem to be
caching/keeping large files.  Attached is my configuration.  Is there
something obvious that I'm missing?
