I would say: Use the second conf posibility described here and enter 2 (or
more) parent caches.

Note: The information here is current for version 2.2.

First, you need to give Squid a parent cache. Second, you need to tell Squid
it can not connect directly to origin servers. This is done with three
configuration file lines:

        cache_peer parentcache.foo.com parent 3128 0 no-query default
        acl all src 0.0.0.0/0.0.0.0
        never_direct allow all

Note, with this configuration, if the parent cache fails or becomes
unreachable, then every request will result in an error message.

In case you want to be able to use direct connections when all the parents
go down you should use a different approach:

        cache_peer parentcache.foo.com parent 3128 0 no-query
        prefer_direct off

The default behaviour of Squid in the absence of positive ICP, HTCP, etc
replies is to connect to the origin server instead of using parents. The
prefer_direct off directive tells Squid to try parents first.

Hi Squid Wizards,

is it possible to set up Squid to use a second parent peer in case the
first parent peer fails? The parents don't talk ICP.

Cheers,
Rainer
