What is a Web Proxy Caching Server?
A proxy caching server is a system which sits between your web browser and the Internet. It acts as an intermediary (or “proxy”) by fetching pages on your behalf, which it forwards to your browser. It also saves a copy of each document it retrieves to form a collection (or “cache”). The next time that a cached document is requested, the server returns it from the cache instead of going off to the internet.
