The Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing technology that intercepts IP packets and redirects those packets to a destination other than that specified in the IP packet.

| WCCP Client | Content Engine/Proxy | A device, such as a Secure Web Appliance (SWA) that receives redirected traffic to either fulfill the request from its local cache or process it further. |
| WCCP Server | Router/Switch | A WCCP-enabled router or L3 switch that intercepts and redirects traffic based on specified service groups |
| ACL | Function | What it controls | Example Devices/Apps |
