tail -f /var/log/squid/access.log lists *plenty* of TCP-MISSes during
normal use
was
"TCP_MISS/200 5042 GET http://www.fsck.com/pub/rt/contrib/ -
DIRECT/www.fsck.com text/html"
now
"TCP_REFRESH_MISS/200 25002 GET http://www.theregister.co.uk/ -
FIRST_UP_PARENT/recycled-02.iinet.net.au text/html"
This is quite useful, especially as the ISP link is faster than mine :-)
Off-Topic :- My ISP has a peering proxy farm with other West Aust ISPs
allowing pages clients of ISP1 download to be cached for clients of ISP2,
ISP3, etc. Last count, it saved the ISPs $740,000 saving 5000 GB of
internet traffic in 30 days. So yeah, I like using proxys :-)

That's correct. As the parent isn't asked, it looks locally (as a result
of the line above), therefore allowing local proxy requests to stay local.
It also helps you, if you do not have a registered domain...
