ANY_OLD_PARENT (former ANY_PARENT?) means that Squid used the first
considered-alive parent it could reach. Squid does that when none of the
specific parent cache selection algorithms (e.g., userhash or carp) were
enabled, all enabled algorithms failed to find a suitable parent, or all
suitable parents found by those algorithms failed when Squid tried to
forward the request to them.
