[squid-users] Refresh ACL list only

I did this once, with external acl, you can specify a ttl of each
external acl and also make your acl reload the list any time you want.

My external acl loaded users (in your case domains) from a list in
hard disk to memory, and then each time squid asked acl verify for a
preset  elapsed time to reuse loaded in memory list or load it again
before answer.

Be aware that dst-domain is a fast acl and you will turn this check
into a slow acl so you should consider if you really need this.

I can provide more details if you decide to use it like this.

Hope it helps
