title: Facebook counter drop to 0 after moving to https
body: <p>Following the instructions given by google folks, I added https support to our blog.</p>
  
  <p>Nginx, behind the scene redirect everything non http to https, proxied to a ruby on rails app.</p>
  
  <p>Everything seems to work quite well but facebook counters appears now buggy.</p>
  
  <p>If you look the source of this page : <a href="https://milesandlove.com/argentine/le-fitz-roy" rel="nofollow">https://milesandlove.com/argentine/le-fitz-roy</a>
  I added a lot of og meta tags :</p>
  
  <pre><code>&lt;meta property="og:url" content="https://milesandlove.com/argentine/le-fitz-roy"/&gt;
  &lt;link rel="canonical" href="https://milesandlove.com/argentine/le-fitz-roy"/&gt;
  </code></pre>
  
  <p>And the share button :</p>
  
  <pre><code>&lt;a class="addthis_button_facebook_like" fb:like:layout="button_count" fb:like:href="https://milesandlove.com/argentine/le-fitz-roy"&gt;&lt;/a&gt;
  </code></pre>
  
  <p>Note that even if its a add_this button, it would be exactly the same result with the official facebook one.</p>
  
  <p><strong>The weird thingis since nobody like the page, it kept showing the old count</strong> . Since a new person came and like the page, it <strong>suddenly reset the counter to 0</strong> !</p>
  
  <ol>
  <li>Is the count definately lost ? </li>
  <li>Why Facebook is protocol aware ?  </li>
  <li>I read that a tricky solution whould be to serve a http:// page to the facebook
  crawler. Is it the only solution ?</li>
