WCCP
You can also configure a FortiProxy unit to operate as a Web Cache Communication Protocol (WCCP) client. WCCP provides the ability to offload web caching to one or more redundant web-caching servers.
WCCP topology
You can operate a FortiProxy unit as a WCCP cache engine. As a cache engine, the FortiProxy unit returns the required cached content to the client web browser. If the cache server does not have the required content, it accesses the content, caches it, and returns the content to the client web browser.
WCCP topology
WCCP is transparent to client web browsers. The web browsers do not have to be configured to use a web proxy.
