i guess what we come down to is this: is it the router's
responsibility to
maintain state on devices around it, or of devices to inform the
router of
their state. imho, its a moot point, but i dare say that it was
probably
easier for cisco to implement the former, as it would have involved
far
less lines coded in IOS than the latter solution.
WCCP maintains "shared state" between cache engines and routers. Unless all entities agree about the state of the world, WCCP is not activated (or will shut itself down to prevent service disruption). It does have very distinct "fail-safe" mechanisms, and is very suitable for maintaining consistent state in a one-to-many as well as many-to-many caching setup because of it. IMHO, that is.
