When a Web Cache Control Protocol-enabled router receives an IP packet, the router determines if
the packet is a request that should be directed to a Cisco Cache Engine. The router looks for TCP as
the protocol field in the IP header and for 80 as the destination port in the TCP header. If the packet
meets these criteria, it is redirected to a Cisco Cache Engine.
Through communication with the Cisco Cache Engines, the routers running WCCP are aware of
available cache engines.

Web Cache Control Protocol Configuration Task List
To use the Web Cache Control Protocol, IP must be configured on the interface connected to the
Internet and the interface connected to the Cisco Cache Engine.
The interface connected to the Cisco Cache Engine must be an Ethernet or Fast Ethernet interface.
