You can also use it set the expiration time, by default it never expire. The expiration is in minutes so laying out the multiplication for a year would be as follows.
Cookie.set('name', 'value', 60*24*365)
The path can also be optionally set as follows.
Cookie.set('name', 'value', 60*24*365, document.location)
Returns the value of the cookie if it exits, 'undefined' if it does not exists.
Removes the cookie with that name if it is set.
Returns a TRUE or FALSE value is the cookie is currently set on the client.
And it's as simple at that! :) Enjoy
