The reverse proxy effectively acts as a gateway between the client, the user, and the application server. It handles all access policy management and traffic routing, and protects the identity of the server that actually handles the request.

For example, an administrator can configure the firewall of a reverse proxy to whitelist or blacklist specific IP addresses. All existing servers behind the proxy will be protected accordingly. Whenever the administrator adds a new back-end server to the network configured to only accept requests from the proxy server, the new back-end server will be protected according to the proxy configuration. Using reverse proxy also allows administrators to easily exchange back-end servers without interrupting traffic. Because the client directly interacts with the proxy, they only need to know its host name and do not need to worry about the change of back-end network topology. In addition to simplifying client configuration, administrators can also configure reverse proxy to load balance traffic, so as to distribute requests more evenly to back-end servers and improve overall performance.
