Ok.

yes.

Squid only implements inter-array CARP forwarding, not intra-array CARP
forwarding. As a result it's only usable in forwarding requests to an
array of caches, not for optimizing the forwarding within an array of
caches.

But it is possible to build a two-layer structure on the same servers,
by running a non-caching CARP frontend layer connecting to the caching
Squids.

But it's not much related to forwarding of requests to the origin
servers. Here weighted round-robin is probably the best unless you need
to keep session state on the servers..
