 Related Information

The document provides Web Cache Communication Protocol (WCCP) support for Cisco IOS® software and
Cisco Content Engine software. WCCP is implemented within software−switching paths of all supported
platforms shown in the table below. WCCP is available for process−, fast−, and Cisco Express Forward−
(CEF−) based forwarding paths.

WCCP, developed by Cisco, specifies interactions between one or more routers (or Layer 3 switches), and one
or more Web caches. The interaction establishes and maintains the transparent redirection of selected types of
traffic flowing through a group of routers. The selected traffic is redirected to a group of Web caches with the
aim of optimizing resource usage and lowering response times.
