Sorry for not making myself clearn, but yes, my query was about CARP in
SQUID.
  Thanks for the advice with the directive "prefer_direct", now that I have
turned this off the client
squid can communicate with the parent. However, as I have noticed in the
access.log of the client squid,
it reads FIRST_UP_PARENT instead of CARP, meaning that the client retrieved
the object form the first
parent in a list of parents and did not apply the CARP hashing algorithm to
select the parents.

How do I configure the client squid so that requests are load balanced
amongt the two parents???

Kind regards,

  Michael.
