title: Setting locale in kohana2
body: <p>How can I change default locale that is defined in locale.php file in Kohana 2.3.4 in runtime?</p>
  
  <p>I use  Kohana::config_set('locale.language', array('en', 'United States')); but after redirect it doesn't work, it gets default value(from locale.php).</p>
  
  <p>Thanks</p>
