title: mp4 video not playing on mobile devices
body: <p>This problem seems related to our server configuration. </p>
  
  <p>I have a video that I want to play with HTML5 video on a website. I use video.js for playback.
  The problem is: the video works on my localhost, but it does <em>not</em> work on the production server.
  I tried two different servers and they work flawlessly.</p>
  
  <p>I Really need it to work on this specific server (it has a load balancer and more punch to handle the load we are expecting)</p>
  
  <p>I am stumped; I don't know <em>why</em> it does not work on this server, I expect it to be an apache config issue because it works on the other servers.</p>
  
  <p>I looked at the response headers, they are identical (see below). The movie encoding should be allright as well as they are playing on mobile devices on the test servers. </p>
  
  <p>TEST SERVER (works):
  HTTP/1.1 200 OK

  Any leads are greatly appreciated.</p>
