Script Name: Javascript Cookie Script

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
