Reverse Cache Proxy

If you distribute a stream to a large number of customers, you can decrease the load on the origin server by caching the stream on multiple cache proxy servers or origin servers. This is commonly referred to as either server acceleration or reverse proxy. Unlike normal cache proxy servers that are placed close to the client and are used to decrease latency and upstream bandwidth, a reverse proxy is placed close to the origin server and is used, in conjunction with load balancing software, to reduce the load on that server.

The following diagram illustrates a reverse proxy. The client calls http://Proxy/Movie.wmv. The reverse proxy determines which origin server to use and either redirects the client to that server or proxies content from that server to the client.
