Introduction
In many organizations, there is the need to have all clients pass through a unique proxy server to go out to the
Internet in order to provide centralized authentication and logging of all outgoing HTTP requests. Cisco
Cache Engine uses Web Cache Communication Protocol Version 2 (WCCPv2) to transparently redirect and
cache such requests issued by the clients. This sample configuration provides high bandwidth and resource
savings for all the traffic that goes to the parent HTTP proxy, and ultimately to the Internet.
