title: PHP Session lost in CodeIgniter IE only
body: <p>I'm losting the session with CodeIgniter and only in Internet Explorer</p>
  
  <p>I send an AJAX request to my first controller:</p>
  
  <blockquote>
    <p>/controller/method1</p>
  </blockquote>
  
  <p>In this method1, I create my session</p>
  
  <pre><code>$this-&gt;session-&gt;set_userdata('user', 1);
  </code></pre>
  
  <p>I send a second AJAX request 5 seconds after the first, to another method:</p>
  
  <blockquote>
    <p>/controller/method2</p>
  </blockquote>
  
  <p>In this method, I try to show the content of the session user</p>
  
  <pre><code>var_dump($this-&gt;session-&gt;userdata('user'));
  </code></pre>
  
  <p>But I got a bool(false) answer.</p>
  
  <p>For information, the session library is autoloaded.
  In Chrome, that works good.</p>
  
  <p>Do you have any idea to solve this problem?</p>
  
  <p>Thanks</p>
