Unfortunately, Amos, no one has written any other compression algorithms
support module. We have to eat what they give.

But no one asked the question - why Squid in production installations
has such a low hit ratio that raises the question of expediency of
application caching proxy. We do believe that this is a caching proxy?

I continue to believe that 20% is unacceptably low cache hit ratio,
given the very aggressive settings and the active use of Store ID. Which
brings us back to the idea of the feasibility of using the SQUID as a whole.
