title: Open graph can resolve relative url?
body: <p>I'm adding Facebook Open Graph meta tag to my site. For example:</p>
  
  <pre><code>&lt;meta property="og:image" content="../images/aa.jpg"/&gt;
  </code></pre>
  
  <p>Does Open Graph take relative URLs?</p>
  
  <p>Otherwise, how can I convert a <em>relative url</em> to an <em>absolute url</em> in <strong>asp.net mvc3</strong> - Is there any available function to do so?</p>
