title: Sharer link with parameter in URL
body: <p>I have a popup window with a Facebook <a href="http://developers.facebook.com/docs/share/">custom share link</a>. </p>
  
  <pre><code>http://www.facebook.com/sharer.php?u=&lt;url to share&gt;&amp;t=&lt;title of content&gt;
  </code></pre>
  
  <p>How can I use a url <code>u</code> with a parameter like <code>http://google.com/?q=bla</code>? It looks like facebook always cut of the parameter.</p>
