- * @cfg {Date} expires The cookie expiration date (defaults to 7 days from now)
- * @cfg {String} domain The domain to save the cookie for. Note that you cannot specify a different domain than
- * your page is on, but you can specify a sub-domain, or simply the domain itself like 'extjs.com' to include
- * all sub-domains if you need to access cookies across different sub-domains (defaults to null which uses the same
- * domain the page is running on including the 'www' like 'www.extjs.com')
