title: OpenGraph - choose where og:url points / redirect user and keep tags working
body: <p>I am trying to implement OpenGraph actions and object. It works fine, I am able to create objects and actions in the ticker/Timelime.</p>
  
  <p>My only concern is when you display the object, its title is a link.
  But it links to the page I use to generate the object, so there is nothing to display :</p>
  
  <p>object.html.erb</p>
  
  <pre><code>&lt;head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# name_space: http://ogp.me/ns/fb/name_space#"&gt;
  &lt;meta property="fb:app_id"        content="APP_ID" /&gt; 
  &lt;meta property="og:type"          content="name_space:object" /&gt; 
  &lt;meta property="og:url"          content="PATH_TO_METHOD_TO_CREATE_OBJECT?img_link=&lt;%= CGI.escape(@img_link)%&gt;&amp;points=&lt;%=@points%&gt;&amp;description=&lt;%= @description%&gt;" /&gt; 
  &lt;meta property="og:title"         content="&lt;%= params[:units_offered] %&gt; Points" /&gt; 
  &lt;meta property="og:description"   content="&lt;%= params[:description] %&gt;" /&gt;
  &lt;meta property="og:image"       content="&lt;%= params[:img_link] %&gt;"&gt;
  </code></pre>
  
  <p>if I change the og:url meta tag to the url of my FB page then the object picks my FB page value..</p>
  
  <p>in a perfect I wanted to link to nothing or my FB page.</p>
  
  <p>Any clue ?</p>
  
  <p>Thanks!</p>
