Name
as_whois_server
Synopsis
This is the hostname of the whois server Squid uses to resolve Autonomous System numbers into IP networks. You only need to worry about this if you use AS-based ACLs (src_as, dst_as).
The default server, whois.ra.net, seems to work relatively well. It may be too far away (and unreliable) for non-U.S. users. If you know of a local whois server that returns AS queries, feel free to use it instead.
