If you can I'd seriously advise upgrading. 2.5 is rather old and even
2.6 is on it planned final release cycle now. If there is any code or
feature reason you have not, please let us know.

Methinks the problem is:
   httpd_accel_uses_host_header off

That option makes accelerators use the Host: header. If it then fails
your ACL, thats a secondary problem with the ACL configuration.


Please use Squid 2.6.STABLE19 or 3.0.STABLE4
