CARP is a hash algorithm. For each given URL there is one CARP parent
that is the designated one.

The weights control how large portion of the URL space is assigned to
each member.

Correct. And it's completely orthogonal to the use of CARP. As I said
most setups do not want to use proxy-only. proxy-only is only useful in
some very specific setups. These setups MAY be using CARP or some other
peering method, the choice of peering method is unrelated to proxy-only.
