Use 'domain' on the Javascript cookie if you are using it on a subdomain, like widgets.yoursite.com, where

It's good practice to not assume the path to the site root will be set the way you want it by default, so do
this manually as a rule, '/'. If no value is set for expires, it will only last as long as the current session
of the visitor, and will be automatically deleted when they close their browser. 

Set the time as milliseconds
