title: How to clear Facebook Sharer cache?
body: <p>We used the link: </p>
  
  <pre><code>http://www.facebook.com/sharer.php?u=[shared URL]
  </code></pre>
  
  <p>...to share a particular page. However, Facebook Sharer uses the cached version of the images and the title. Is there a way to quickly clear the Facebook cache or how long do we have to wait until the data gets updated?</p>
  
  <p>I placed <code>&lt;link rel='image_src' href='[preview image]' /&gt;</code> in between the  tags.</p>
