title: Facebook open graph changed my https link to http when I post to timeline
body: <p>I would like to post an Open graph object to Facebook. Every link is HTTPS but after post to Facebook, it shows error:</p>
  
  <p>This story was invalidated because: The object at [http://minifacebook.co.kr/music/post_open_graph?fb_source=profile_multiline&amp;fb_action_types=listenns%3Alisten&amp;fb_action_ids=181400501941476] doesn't have a title.</p>
  
  <p>It seems FB changed HTTPS protocol to HTTP. I posted following link:</p>
  
  <p>[https://minifacebook.co.kr/music/post_open_graph]</p>
  
  <p>Moreover, I used [http://developers.facebook.com/tools/debug] to test above link. They show different results when I use <a href="https://minifacebook.co.kr/music/post_open_graph" rel="nofollow">https://minifacebook.co.kr/music/post_open_graph</a> and <a href="http://minifacebook.co.kr/music/post_open_graph" rel="nofollow">http://minifacebook.co.kr/music/post_open_graph</a></p>
  
  <p>Is there any clues?
  Thank in advance.</p>
