No, I agree .. it shouldn't matter at all, but when I don't have much controle
over the application it's nice to verify that it works both in theory *and* in
practice :-) Otherwise the customers might get unhappy, and we might get forced
to use a system with sticky sessions towards each server.
IMHO, seeing that this works, we now have a very nice scalable system, without
too much complexity (simple failover ip-address)-- and also no single points
of failure.
