RE: Problems with parent proxy using squid 2.3 STABLE 2

This was the problem! I was using squid 2.1 PATCH 2 and everything was
working fine. When I upgraded to squid 2.3 STABLE 2 and used the same
squid.conf file, the parent functionality was broken. However, after adding
the never_direct lines things worked again.

Thank you for the help,

Squid-2.2 and later more or less ignores non-ICP peers (no-query) unless
"prefer_direct off" or "never_direct allow" is used (prefer_direct off
to make it prefer to use parents over direct or never_direct allow to
force it to use parents).
