WCCP talk..

[alex () nac net]

Unfortunately, stage fright prevents me from asking this question on the
NANOG meeting floor.

My understanding of WCCP is that the server is responsible to tell the
WCCP-enabled Cisco router that, "Hey, I'm alive to recieve port 80
requests!"

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

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.
