--> WCCP stands for Web Cache Communication Protocol.
--> WCCP is mainly used in transparent proxy deployments.
--> Web Cache Communication Protocol (WCCP) is a protocol which transparently redirects users to cache server, without them having to configure proxy settings in their browsers.
-->In order WCCP to work, we need Layer 3 device and Cache Engine.
--> Layer 3 device can be Router or ASA or Layer 3 Switch.
--> If you want to implement WCCP on Layer 3 Switch then set the SDM template to routing.
--> WCCP helps to reduce network bandwidth by storing web pages in cache engine.
--> WCCP works in following steps
i) A client sends the traffic.
ii) Traffic is received by the router and then redirected to Cache Server or WSA by creating GRE tunnel.
iii) If the requested content is present in cache engine then WSA simply forwards the content otherwise it forwards the request to the Internet.
--> In order to router to tell which traffic to be redirected to WSA, we need to create service groups.
--> Service Groups can be Standard or Dynamic.
--> WCCP can be Version 1 or Version 2.
--> Iron Port Supports only WSA version 2.
