Streaming XHR cache control (Windows)

In Internet Explorer 11 you have more control over whether or not data you download using XMLHttpRequest (XHR) is written to the disk, or cached, before it's passed to the video control using the msCaching attribute. When you download video data using XHR, you can use the msCaching attribute to control whether to write the data to disk (cache), or not, to save power and decrease playback latency.

IE11のxhr.msCaching = 'disabled'で、ディスクへの書き込みを抑制してモバイル端末のバッテリーを節約。video stream用途を想定しているらしい。
