There is also a weird side-case rarely seen with dstdomain thst needs
checking here.

Mario:
  does it work if you change the ACL line to:
   acl server1_acl dstdomain .xyz.example.com

If not, check your config for lines mentioning always_direct or
never_direct, and the network linkage between test proxy and web server
as mentioned by Chris.
