RE: [squid-users] CARP on a flat (no hierarchy) set of SQUID servers???

Kinkie,

Thank you for the Information. Looks like because of load I'm going to
use a three tier approach, F5, a pair of squids just for the CARP
function (with caching virtually disabled, as you suggest), and about 12
Squids with for the data.

Will the CARP algorithm have the same result on two different boxes, if
the configs are the same? I.e. will it "point" at the same squid?

CARP is a parent selection algorithm, so it only works in a hierarchy.
I do not really understand what you mean by "above" and "below"; you
might want to use a squid in place of the F5 load balancer (you can use
keepalived/vrrpd to achieve high availability at the system level). This
is assuming that a single squid with caching essentially disabled can
handle the network load.

Otherwise there's no alternative than using two layers of squids.
