?huh? your example omits cache_peer order.
Which is half the critical config for failover sequencing.

ok this squid.conf seems to be working for me. sans cache-mgr stuff.

Basically I wanted an inexpensive solution for redundancy, hosting many
sites on inexpensive equipment. The current test: With four servers, 2
squid machines and 2 main servers - if one goes down everything still
works. If a squid machine and a main server goes down at the same time
then everything still works. If both squid machines or both main servers
go down, then I'm SOL but that's unlikely... They're spread out
geographically so it would 'prolly take something like a nuclear war for
that to happen. (crossing fingers).
The squid machines are also ns servers, which say 'i'm master of domain
x, i serve http for domain x' - the domain in question. So the
redundancy begins at the nameserver field in the domain record.
So it seems to work so far with my limited test, I'll see what happens
if I set up a bunch of domains. It also seems scalable.
However, you mentioned "cache_peer order" - it seems to go in the order
specified in squid.conf - i've reviewed the docs - i don't see a
parameter to set the order?? just checking. maybe i missed something.
