I was under the false impression that content on "local_ip" networks
wasn't cached, which was my goal.

Duane informed me that 1.2 will have a "no_cache_acl".

The script is done. It is in perl and uses the Net::Telnet module
and does the following.

1. telnets to a cisco router
2. grabs output of "show ip bgp"
3. CIDRs "classfull" networks and does a little agregation
4. Rewrites the squid.conf file with a new sorted "local_ip" line
5. Sends "squid" a HUP signal

I have it running out of cron once a week.

It would be easy to modify it to use an external acl file and the new
"no_cache_acl" with 1.2.

If anyone wants a copy, send me an email.
