title: Cakephp Session issue with chrome and firefox
body: <p>I am trying to use common session across two sub-domains using cakePHP. On my local setup its working fine in all the browsers but on server its working only in IE.</p>
  
  <p>Following is the code i use in core.php</p>
  
  <pre><code>Configure::write('Session', array(
      'defaults' =&gt; 'php',
      'cookie' =&gt; 'PHPSESSID',
      'timeout' =&gt; 20000, // 1 hour
      'ini' =&gt; array(
      'session.cookie_domain' =&gt; '.dummy.com.au',
      'session.gc_maxlifetime' =&gt; 36000 // 1 hour
      )
  ));
  </code></pre>
  
  <p>I have set security level to low</p>
  
  <pre><code>Configure::write('Security.level', 'low');
  </code></pre>
  
  <p>But its still not working.</p>
