title: CodeIgniter's sess_destroy doesn't work
body: <p>I have this controller:</p>
  
  <pre><code>    function Logout() {
          $this-&gt;session-&gt;sess_destroy();
          redirect('/');
      }
  </code></pre>
  
  <p>Pretty straightforward. But it doesn't work. As simply as that - sessions are stil stored. I tried using <code>unset_userdata</code> with all my sessions (two at the moment), but it doesn't work also.</p>
