Ah, your squid.conf only lists this as the one and only accelerated domain:
acl our_sites dstdomain protected_domain.com
This is whats is happening:
browser requests http:/protected_domain.com/ for example
When Apache sees that it sends a reply (301 location changed) to cause the
browser to make a brand new request for www.protected-domain.com.
Squid sees that new requests as a non-accelerated one (due to the ACL not
matching) and handles it as a regular web request. With DNs pointing those
regular requests at Squid it asks itself on port 80 for
www.protected-domain.com and loops.
To fix it make the ACL:
acl our_sites dstdomain .protected_domain.com
