I find that larger files are only worth caching for a short time
because if there's a chance I might want them again I'll save them
(out of the cache).

I had a cursory look at the heap policy implementations and got the
impression that the heap keys are recomputed when the squid process
starts-up. If that's correct then the LFUDA and GDSF implementations
are only really suitable for systems with very long squid up-times. In
my case I turn my PC off on most nights rendering the aging mechanism
useless.

AFAIK purge only deletes by URL, not combinations of age and size.
"purge -ve." can generate a very detailed object listing though, which
might be useful if I ever get around to writing a script.
