Configuring Web Cache Services By Using
WCCP
This chapter describes how to configure your Catalyst 3550 switch to redirect traffic to cache engines
(web caches such as the Cisco Cache Engine 550) by using the Web Cache Communication Protocol
(WCCP). WCCP is a Cisco-developed content-routing technology that you can use to integrate cache
engines into your network infrastructure. The cache engines transparently store frequently accessed
content and then fulfill successive requests for the same content, eliminating repetitive transmissions of
identical content from web servers. Cache engines accelerate content delivery and ensure maximum
scalability and availability of content. In a service-provider network, you can deploy the WCCP and
cache engine solution at the points of presence (POPs). In an enterprise network, you can deploy the
WCCP and cache engine solution at the regional site and the small branch office.
To use this feature, you must have the enhanced multilayer software image (EMI) installed on your
switch.
For complete syntax and usage information for the commands used in this chapter, refer to the "WCCP
Note
Router Configuration Commands" section in the "Cisco IOS System Management Commands" part of
the Cisco IOS Configuration Fundamentals Command Reference for Release 12.2.
