cache digest

Hi,

Assume that I have two parents, both are using only CDs, but not ICP. The
squid.conf argues to use the "round-robin" in order to distribute the load
between the two parents. In the absence of "round-robin", it appears as if
the first cache_peer cache will be used for most requests unless down. So,
requesting a typical home page would store half of the objects on one
cache and the other half on the other cache. Only after the next CD
refresh will client cached be informed of this fact.

Wouldn't it be possible to use CDs to determine the parent which is more
likely to store the objects, and route the request there using the
likelihood as a kind of 'weight' instead of clean round robin? I guess
that would call for yet another option to cache_peer. The reason I am
suggesting this, I may be on the wrong track here, is that I believe it
also beneficial to lowering the false HITs besides keeping objects
together which are grouped on page view level.
