Note that squid doesn't consider the core file part of it's cache,
it's just an arbitrary file in that directory, not part of the cache...

hmm - There is supposedly a bug like this in that squid may continue to
clear the cache after the min value has been reached...

I was sent this patch by Duane, since we were one of the first
people who used NOVM... strangely the patch isn't listed on the
home page... (Duane? - As far as I know you are holding the cache-conference
so there isn't much chance of you answering this...)
it seems to match the symptoms described...

Using CIDR notation works...
etc should work.

Hope that it helps...
