The WMS Cache Proxy plug-in in Windows Media Services 2008 is 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. This section describes how to enable and configure the plug-in.

When you configure the Windows Media server as a cache/proxy server by enabling and configuring the WMS Cache Proxy plug-in, 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) are created in Windows Media Services. These default publishing points allow you to monitor and configure additional properties for managing your Windows Media server as a cache/proxy server. For more information, see About the Monitor tab for a publishing point and About the Properties tab for a publishing point.


Ports must be opened in the firewall on this server so that it can update content in its cache using a protocol that you select. For more information, see Firewall Reference for Windows Media Services 2008. In addition, on the origin server, the appropriate server control protocols must be enabled. For more information, see Selecting 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 Configuring a Windows Media server as an origin server.
