Reverse proxy (IP forwarding)
IP-forwarding topologies use a reverse proxy server, such as the Caching Proxy, to receive incoming HTTP requests and forward them to a Web server. The Web server forwards the requests to the appservers for actual processing. The reverse proxy returns completed requests to the client, hiding the originating Web server.
If a client then requests the same data next time, it will not be sent to the back-end server for processing, but instead will be served from the cache. This prevents unnecessary back-end processing for the same data requests, thus providing better response times.
