title: Problem in facebook share functionality
body: <p>I have a facebook iframe application where i have provided a share functionality. I am using this code :</p>
  
  <pre><code>&lt;script&gt;
      function fbs_click()
      {
          u='&lt;?php echo $shareURL;?&gt;';
          t=document.title;
          window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&amp;t='+encodeURIComponent(t),'sharer','toolbar=0,status=0,width=626,height=436');
          return false;
       }
  &lt;/script&gt;
  &lt;style&gt;
      html .fb_share_button {
       display: -moz-inline-block; display:inline-block;
       padding:1px 20px 0 5px; height:15px; border:1px solid #d8dfea;
       background:url(http://b.static.ak.fbcdn.net/rsrc.php/z39E0/hash/ya8q506x.gif)
       no-repeat top right;
      }
       html .fb_share_button:hover {
        color:#b5b8d3; border-color:#295582; background:#3b5998
        url(http://b.static.ak.fbcdn.net/rsrc.php/z39E0/hash/ya8q506x.gif)
        no-repeat top right; text-decoration:none;
       }
  &lt;/style&gt;
  
  &lt;a href="http://www.facebook.com/share.php?u=&lt;url&gt;" class="fb_share_button" onclick="return fbs_click()" target="_blank" style="text-decoration:none;"&gt;Share&lt;/a&gt;
  </code></pre>
  
  <p>The problem i am facing is that if i pass u to my site url then inside share box title is properly displayed but when posted to my profile, clicking on the link redirects me to outside of my facebook application which i don't want i want it to remain inside facebook page.
  However if i change u parameter to something like <a href="http://apps.facebook.com/app/" rel="nofollow noreferrer">http://apps.facebook.com/app/</a> then inside share box the title is  showing apps.facebook.com and when posted on my profile, clicking on it redirects me inside the facebook application but onto a new tab.</p>
  
  <p>I just want the title should be set according to the value passed and if i click on it on my profile page it should remain inside facebook.</p>
