Anytime static data is stored to speed up access to it, it is using a method called caching. Usually this is called a proxy cache or a web cache.

Proxy servers are useful for serving Internet pages, so for example if a user request the same page more than once they the proxy has cache of that page and serves your browser. Another thing is that the proxy can be used for security and in these case its between your browser and the WWW.

A proxy server, also known as a "proxy" or "application-level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the internet. Proxy servers provide increased performance and security.
