Squid over 2 machines?

Hi,.
        Is it possible to set squid up, so if one machine on the network
dies, it automatically uses the other machine as a backup cache??
If so how could it be done?

Cheers,

Out the 10Base-T, through the router, down the T1,
over the leased line, off the bridge, past the
firewall... nothing but Net.
