This topic discusses a type of behavior that a cache/proxy
plug-in could provide when used with Windows Media Services. The
cache/proxy plug-in you obtain or create may behave
differently.
After a cache/proxy plug-in is installed on a Windows Media
server it can provide the ability for your server to proxy a live
stream from an origin server through another Windows Media server.
When a client requests a live stream, the
cache/proxy 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.
Notes
To view a list of partners that provide
cache/proxy plug-ins for Windows Media Services 9 Series, see the
