RE: WCCP and WAEs

It's due to the nature of these two services and the way they handle load
distribution.

We're working on an article to explain how to design an optimized WAN based on
best practices. I'll post it to CCBOOTCAMP forum or blog in very near future.

Would you please share why is that ? Or is it sort of black magic ? :)

I would agree that if you have very few IP addresses on either side,
and you have more than one WAE to choose from, then I would base the
hash on the side that actually has many IPs, for the sake of having a
smooth distribution.

Is there any other thing that has to be accounted at design time ?

P.S.
Original question was if the assignment was related (branch/central).
Technically it is not, from the above design point of view, it is,
and the original setting makes sense, because if you have more clients
than servers, it makes sense to hash on clients, which are LAN side
at the branch and WAN side at central.
