Cache/Proxy plug-ins control the ability of your Windows Media server to perform caching and proxy functions. You can obtain third-party cache/proxy plug-ins from a Windows Media-based caching partner or by creating your own by using the Windows Media Services Software Development Kit (SDK).
To view a list of Windows Media-based caching partners, or to download a copy of the Windows Media Services SDK, see the Windows Media home page at the Microsoft Web site.
