Proxying a live stream
Applies To: Windows Server 2008, Windows Server 2008 R2
The WMS Cache Proxy plug-in in Windows Media Services 2008 allows the cache/proxy server to proxy a live stream from an origin server through another Windows Media server. When a client requests a live stream, the plug-in checks whether the cache/proxy server is already proxying the stream. If the server is not proxying the stream, the plug-in requests that the cache/proxy server open a connection to the origin server. After establishing a connection to the origin server, the cache/proxy server streams the content from the origin server to the client. If the cache/proxy server is already proxying the stream, the plug-in requests that the server split the stream so that all requesting clients can receive the content. In this way, there is only one connection between the cache/proxy server and the origin server. The content is not cached because a live stream does not have a file associated with it.
