  <p>Well its not an problem that i am facing since its not mixing up in any way with my code, but just an curiosity to know why the URL of my app gets appended by this extra characters as #<em>=</em>  when user logs into my site using Facebook api ?</p>
  
  <p>For eg my url should be</p>
  
  <pre><code> www.xyz.com/viewResume
  </code></pre>
  
  <p>but it actually is </p>
  
  <pre><code> www.xyz.com/viewResume#_=_
  </code></pre>
  
  <p>Any particular reason for this behaviour ?
  Am using Codeigniter Framework</p>
