Cache/Proxy management plug-ins are used to configure a Windows Media server either as a cache/proxy server or as a reverse proxy server so that it can provide caching and proxy support to other Windows Media servers. Windows Media Services contains the following cache/proxy management plug-in:
Ports must be opened in the firewall on this server so that it can update content in its cache using the selected protocol. For more information, see Using firewalls. In addition, on the origin server, the appropriate server control protocols must be enabled. For more information, see About data transfer protocols.
Cache/proxy properties must be configured on the origin server to specify how often this server checks for updated content. For more information, see Cache/Proxy.
When you enable this plug-in, you can monitor and configure additional properties for the default publishing points named Cache/Proxy On-Demand (for caching and streaming on-demand content from the origin server) and Cache/Proxy Broadcast (for proxying live content from the origin server). For more information, see Managing cache/proxy publishing points.
