title: Open Graph - Change og:url in post
body: <p>Here is the scenario:</p>
  
  <p>Site A - has the open graph tags and when a user hits the page a frictionless timeline post is made.
  Then, when a person clicks on that post I want to direct them to Site B.</p>
  
  <p>I've already figured out how to make successful posts to timeline from Site A.</p>
  
  <p>Any ideas on how I can force a different URL for the title, image, etc from the site a post was made?</p>
  
  <h2>OG Meta Tags:</h2>
  
  <pre><code>&lt;meta property="fb:app_id" content="&lt;%= @graph.fbappid %&gt;"/&gt;
  &lt;meta property="og:type" content="&lt;%= @graph.ogtype %&gt;"/&gt;
  &lt;meta property="og:title" content="&lt;%= @graph.ogtitle %&gt;"/&gt;
  &lt;meta property="og:description" content="&lt;%= @graph.ogdesc %&gt;"/&gt;
  **&lt;meta property="og:url" content="&lt;%= @graph.ogurl %&gt;"/&gt;**
  &lt;meta property="og:image" content="&lt;%= @graph.ogimage %&gt;"/&gt;
  &lt;meta property="video:actor" content="&lt;%= @graph.ogactor %&gt;" /&gt;
  </code></pre>
  
  <p>The <code>og:url</code> references the page from which a post is made. However, I want the user to be directed to a different page when the click on the post.</p>
