title: Facebook comments widget over HTTPS/SSL security warning in IE7 & IE8
body: <p>I am attempting to add the Facebook comments widget to a page that is being served over SSL/HTTPS. The widget works fine, but when I attempt to load the page in IE7 or IE8, I get a "mixed content" Security Warning.</p>
  
  <p>I've gone through and verified that we are not referencing any insecure resources in the page. Removing the facebook comments widget makes the warning disappear. Using fiddler, I tried to pinpoint the resource that is being referenced, but as far as I could see, nothing is being pulled over http. I've confirmed the issue with a minimal repro case that just has the comments widget on the page.</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en-us" xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"&gt;
    &lt;head&gt;
      &lt;title&gt;
        Test FB Comments
      &lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div class="fb-comments" data-href="https://www.example.com/fb_minimal.html" data-num-posts="10" data-width="470" data-colorscheme="light"&gt;&lt;/div&gt;
      &lt;div id="fb-root"&gt;&lt;/div&gt;
      &lt;script type="text/javascript"&gt;
        window.fbAsyncInit = function () {
          FB.init({ appId: 'MY_FACEBOOK_APP_ID', status: true, cookie: true,
            xfbml: true
          });
        };
        (function () {
          var e = document.createElement('script'); e.async = true;
          e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
          document.getElementById('fb-root').appendChild(e);
        } ());
      &lt;/script&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>This loads without warning in other browsers (Chrome, Firefox, IE9 and above).</p>
  
  <p>I've reviewed my facebook application settings and everything appears to be configured correctly, although I am new to facebook integration, so perhaps I've missed something.</p>
  
  <p>I've looked at this thread, <a href="https://stackoverflow.com/questions/5212016/facebook-javascript-sdk-over-https-loading-non-secure-items">Facebook JavaScript SDK over HTTPS loading non-secure items</a>, but none of the suggestions there had any effect. I suspect this issue is different, since I'm not seeing warnings in other browsers as well.</p>
  
  <p>Any insight would be greatly appreciated.</p>
