Web Cache Communications Protocol (WCCP)

Introduction

The Web Cache Communication Protocol (WCCP), developed by Cisco Systems, specifies interactions between one or more routers (or Layer 3 switches) and one or more web-caches. The purpose of the interaction is to establish and maintain 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.
