Proxy Web Servers and Authentication

What are proxies?

A proxy is a service that sits between web servers (or, more accurately, "origin web servers") and clients. This service receives requests from clients and makes requests to servers on behalf of the clients.

A caching proxy, in addition to the above, saves a copy of the HTML pages, graphics, and other resources as they pass through.
