Overview

Acting as a reverse proxy, or a forward proxy, Caching Proxy intercepts data requests from a client, retrieves the requested information from content-hosting machines, and delivers that content back to the client. Most commonly, the requests are for documents stored on Web server machines (also called origin servers or content hosts) and delivered via the Hypertext Transfer Protocol (HTTP). However, you can configure Caching Proxy to handle other protocols, such as File Transfer Protocol (FTP), and Gopher.

Caching Proxy stores cacheable content in a local cache before delivering it to the requester. Examples of cacheable content include static Web pages and JavaServer Pages (JSP) FILES with dynamically generated but infrequently changing fragments. Caching enables the Caching Proxy to satisfy subsequent requests for the same content by delivering it directly from the local cache, which is much quicker than retrieving it again from the content host.

IMPORTANT: Caching Proxy is available on all Edge component installations, with the following exceptions:
