WCCP Cache Registration

WCCP defines the router as a server and the proxy as a client. The proxy registers
with the WCCP server (configurable between 0-255) and sends a “Here I Am”
message every 10 seconds. The router (WCCP Server) responds with an “I See You”
message. If the “Here I Am” message misses on 3 consecutive tries (30 seconds), the
proxy is marked as failed
