I do not care if someone asks even if the docs are answering.
The docs of squid-cache are not something anyone should be able to remember by heart or even browse and just "find" a solution or a direction.
We(at least me) are here to try and help even for the cases which the docs already cover.

All The Bests,
Eliezer

Ok. Looks like 3.5.20 is the latest on the yum repo I'm using, so guess
I'll have to learn how to compile it myself; never compiled a package
before.
