title: Iframe loading/buffering issue
body: <p>I am currently having some issues that I believe to be related to an iframe.</p>
  
  <p>My website homepage has a video on, with a simple "play" button that when pressed will load on iframe with a url from my root, video.html with a embedded to play.</p>
  
  <p>My site is load-balanced, I had no issues with apache 2.2 but now i am using apache 2.4.</p>
  
  <p>The video and frame loaded instantly with 2.2, but in 2.4 I click the button - the audio for the video starts playing, but the tab is loading something and soon after the video appears. </p>
  
  <p>I can close the video and reopen and it does the same thing. In all browsers</p>
  
  <p>I can visit the referenced URL in the iframe to pull the video from via the balancer and it plays right away.</p>
  
  <p>Anyone know what sort of configuration element i may be missing? :)</p>
