Re: Auto-bypassing a parent when parent is down

The problem, Duane, is that in many cases the costs of bandwidth coming
off proxy servers is much reduced. Therefore, site setups want to
absolutely forbid squid to fetch directly for ANY reason whatsoever
_unless_ the parent(s) should go down, not be reachable etc.

inside_firewall fits the first order of business, prevent lots of messy
and expensive direct traffic, but things go haywire if connectivity to
your parent(s) is lost.
