title: Does facebook video embed follow og:video redirect?
body: <p>I have a page with a video on it .. say (<a href="http://example.com/123" rel="nofollow">http://example.com/123</a>) and it provides all the og: meta tags for facebook... so when I make a post on FB with that url, facebook would automagically embed that video into the post.   open graph tags such as these:</p>
  
  <pre><code>&lt;meta property="og:title" content="My Title" /&gt;
  &lt;meta property="og:description" content="This is a description." /&gt;
  &lt;meta property="og:video" content="https://example.com/player.swf?id=123&amp;autoplay=on&amp;blah=12345&amp;etc"/&gt;
  &lt;meta... etc. etc&gt;
  </code></pre>
  
  <p>This works great.  However, I have a bunch of parameters on that swf player that I don't want facebook embed code to cache.  For example, i might have the parameter</p>
  
  <pre><code>autoplay=on
  </code></pre>
  
  <p>but if hardcode that into the og:video string, all videos embedded has autoplay turned on by default and would be hard to change.  Hence I want to have a level of indirection like:</p>
  
  <pre><code>&lt;meta property="og:video" content="https://example.com/redirswf/123" /&gt;
  </code></pre>
  
  <p>where /redirswf/123 would redirect to the original full player.swf url</p>
  
  <p>I tried this but when I post the url to FB, the video just doesn't play.  I'm not sure how to debug this.. all I can think of is that FB is not following the 302 redirect when it tries to go to redirswf/123?  can anyone confirm or deny?</p>
  
  <p>And I did confirm via the facebook debugger tool that it's pulling out the og:video field as expected:</p>
  
  <pre><code>{
      "url": "https:\/\/example.com\/redirswf\/123",
      "secure_url": "https:\/\/example.com\/redirswf\/123",
      "type": "application\/x-shockwave-flash",
      "width": 640,
      "height": 360
  }
  </code></pre>
