Forward proxy
The Caching Proxy can be configured as a forward proxy. Normally Internet access providers configure in this mode. When configured in this mode, it handles requests from multiple client browsers, retrieves data from the Internet and caches the retrieved data for future use. In this case, the client browser has to be configured to use the proxy server. When a client requests a page, the caching proxy forwards it to the content host located across the Internet, then caches the retrieved data and delivers the retrieved data to the client. If someone else requests the same page the next time, it will be served from the cache. This decreases the network usage and gives better response times.
