Please begin by running "squid -k parse" and fix all the warnings and
errors it reports.

Also;

* "cache deny CONNECT" is pointless. CONNECT traffic cannot be cached.

* a series of "allow" lines followed by an "allow all" is usually
pointless. Just use one line doing "allow all".
 - same for a series of "deny" lines followed by a "deny all".

* For all the lines you have which do this pattern:
"
 ... allow/deny __domain__squid_2
 ... allow/deny CONNECT __domain__squid_2
"
 that second line is pointless. The first line already matches and
allows/denies the CONNECT traffic which the second might match.


Then add "nonhierarchical_direct off".

If you still have problems after all that, pelase provide a bit more
details about what you see that is telling you its "not working".
