  Script Name: Javascript Cookie Script
  Author: Public Domain, with some modifications
  Script Source URI: http://techpatterns.com/downloads/javascript_cookies.php
  Version 1.1.1
  Last Update: 4 October 2007

  Changes:
  1.1.1 fixes a problem with Get_Cookie that did not correctly handle case
  where cookie is initialized but it has no "=" and thus no value, the 
  Get_Cookie function generates a NULL exception. This was pointed out by olivier, thanks

  1.1.0 fixes a problem with Get_Cookie that did not correctly handle
  cases where multiple cookies might test as the same, like: site1, site
