FeedbackIntroduction
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.
