Introduction
The Cisco Content Services Switch (CSS) series can support smart proxy and transparent caching. The Cisco Content Services Switch can also support Web acceleration through intelligent reverse-proxy caching. There are several balancing methods available, which depend on how you like to distribute data over the caches (for example, whole URL, URL string, whole domain name, domain string, and so on). The Cisco Content Services Switch automatically builds a list of known cacheable objects. It is possible for the list to be modified, but much of the work is reduced.
This document provides a sample configuration for proxy caching.

Network Diagram
This document uses the network setup shown in the diagram here:
Configuration
The proxy clients come in on the proxy port (8080), and are mapped to the cache server on port 80 in this configuration. Generic servers can be used to emulate the proxy servers. The Web servers can be replaced with cache servers if they are available.

Verify
This section provides information you can use to confirm your configuration functions properly.
Since a real cache server is not used for the proxy cache test, append :8080 to the URL. For example, http://10.1.1.100/1.html:8080.
Troubleshoot
There is currently no specific information available on how to troubleshoot this configuration.
