My question is, what prevents a cache from seding a WCCP frame saying, "Hey, I'm alive" when it really isn't?

the application itself (layer 7) is most likely to know more about whether the application is alive and working than anything else.

Is there a way for the router to check the cache in the opposite direction? Seems odd that your would rely on the cache to verify that the cache is OK.

i believe WCCP is more a heartbeat mechanism - the router will age WCCP 'hello' packets and expire them. presumably if it doesn't hear one of the cache engines 'check in', it'll stop forwarding traffic to it. cheers, lincoln.
