Script Name: Javascript Cookie Script
Author: Public Domain, with some modifications
Script Source URI: http://techpatterns.com/downloads/javascript_cookies.php
Version 1.1.2
Last Update: 5 November 2009

Changes:
1.1.2 explicitly declares i in Get_Cookie with var
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
