What is Reverse Proxy?

A service or server that offloads Web publishing responsibilities from Web servers and allows you to securely connect a company’s internal Web servers to the Internet or to the rest of the company intranet. In reverse proxying, a proxy server is used to impersonate a Web server to the outside world.

The proxy server receives client requests for Web content and fulfills these requests from its cache. It forwards client requests to the actual Web server only if it cannot serve the requests from its own cache.

Microsoft Proxy Server supports reverse proxying so that you can publish to the Internet without compromising your internal network’s security. Proxy Server uses reverse proxying to send client requests downstream to a Web server or group of Web servers that are located behind the proxy server.

This configuration results in improved Web server capacity planning, protects the security of data while allowing access to the Internet, and allows Web servers to access other servers on the internal network for publishing purposes.
