title: Facebook Comments Plugin for different articles on IP.Content
body: <p>I'm trying to add facebook comments plugin to the IP.Content articles with following code</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  
  &lt;meta property="fb:app_id" content="{YOUR_APPLICATION_ID}"&gt;
  
  &lt;/head&gt;
  
  &lt;script src="http://connect.facebook.net/en_US/all.js#xfbml=1"&gt;
  &lt;/script&gt;
  
  &lt;body&gt;
  
  &lt;div id="fb-root"&gt;&lt;/div&gt;
  
  &lt;fb:comments href="YOUR_CANONICAL_URL"&gt;&lt;/fb:comments&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Can anyone explain me what is YOUR_CANONICAL_URL ?
  If I'm putting my website url , anyone who commets the article that shares the meta description of my main page on the his wall.</p>
  
  <p>What link I need to insert to make displaying the link to the article on anyone who commets wall.</p>
  
  <p>There was something like  <code>&lt;?php echo rand(); ?&gt;</code> to be added to the link....but I'm not quite good in that php tricks....</p>
  
  <p>Also I'm putting that code into global articles view template. But for that reason comments are the same for all articles. How can I make them be different for each article ?</p>
  
  <p>Thank you for any replies on that subject... </p>
