title: Does IIS7 cache video(mp4/wmv) files?
body: <p>We are building a video application, videos would be stored on the file system of the web-server and contents are being served by IIS7(W2K8).</p>
  
  <p>We would like to improve the performance of the content delivery and cache the video files(as expected that users would be accessing only top 50videos on a daily basis), Does IIS7 cache video(mp4/wmv) files by default? </p>
  
  <p>If not, is there a way to let the IIS7 to cache the video files?</p>
