Introduction
The Web Cache Communication Protocol (WCCP) was initially designed as a component of IOS whose purpose was to intercept HTTP traffic traversing a router and redirect that traffic to a local cache with the aim of reducing access times to web sites and conserving wide area bandwidth. Typically the packets are redirected from their destination web server on the Internet to a content engine that is local to the client. In some WCCP deployment scenarios, redirection of traffic may also be required from the web server to the client. WCCP enables you to integrate content engines into your network infrastructure. With the introduction of WCCPv2 the scope of the protocol widened to include traffic types other than HTTP allowing the protocol to be used as a more general interception mechanism. In WCCPv2 clients specify the nature of the traffic to be intercepted and forwarded to external devices which are then in a position to provide services, based upon the traffic type, such as WAN optimisation and application acceleration.
This document should give the current suported features and options for WCCP. It is structured per device as using a matrix would be unwealdy.
For modern versions of IOS there is 'show ip wccp capabilities' which gives more or less the same info.

Is there an updated version of this covering the ISR 4000 series routers? Or can someone help with the recommended WCCP settings for the ISR 4000 series? Will L2 redirects work fine with minimal CPU load?
