That is the correct design.  It does not work for you because you put
the wrong domain name in the domainAT ACL.


Look at the log carefully. See how the domain the client is asking for
is actually "www.voeazul.com.br". Even a single character difference
makes it an entirely different domain name - the "www." bit matters.


If you want domainAT to do exact-match then you need to add the www.*
sub-domain to the list. Like this:
 acl domainAT dstdomain voeazul.com.br www.voeazul.com.br


Or, you can use a wildcard (start with a '.') to match that domain and
all its sub-domains. Like this:

  acl domainAT dstdomain .voeazul.com.br

What Squid version are you using?

I see config options which are only valid for Squid-3.1 your setup. If
you are using an old Squid please try an upgrade, or start planning to
do one. There are many security vulnerabilities which affect those very
old Squid-3 and some cannot be fixed there, so even versions with LTS
security support are vulnerable.
