That should be a single line. Is it actually spread over multiple in
your squid.conf? that may be the problem right there.

The above will only match invalid URLs which start with
"http://cyberdyne-intranet/". If the client does the right thing and
adds .local or some other internal domain FQDN suffix this ACL will
fail.

You should have a proper domain name for internal use in both clients
and configs like this (ie cyberdyne.local is a valid FQDN).

same wrap problem for this one.

Er. not good, for two reasons.

  1) "all" means the entire Internet.

  2) this sits before any proxy_auth ACLs are tested (dont see one below
either). Which means your auth will never happen.

Exactly what access control policies is this config meant to be
enforcing?

Your Squid version does not accept config lines indented with
whitespace like that.
The debug_options directive takes a series of number *pairs* as in:
section,level section,level section,level
  eg debug_options ALL,0 1,?? 34,?? 78,??

level 1-6 cover most useful debug info when you need a details action
report.

That is a piece of documentation. Check that it is not actually in your
file.
