Remarks
The CacheRequest class supports offline playback scenarios. When the SmoothStreamingMediaElement needs a chunk or manifest, it first checks with the registered cache plug-in. If the plug-in has it, the chunk is used. Otherwise, SSME downloads it by HTTP. After the download, SmoothStreamingMediaElement provides an option for the plug-in to persist the downloaded chunk.
A template example for implementation of the cache plug-in ships with Microsoft Expression Encoder 4.
