+/**
+ * @class Ext.state.CookieProvider
+ * @extends Ext.state.Provider
+ * The default Provider implementation which saves state via cookies.
+ *
Usage:
+
+ var cp = new Ext.state.CookieProvider({
+ path: "/cgi-bin/",
+ expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
+ domain: "extjs.com"
+ });
+ Ext.state.Manager.setProvider(cp);
+
+ * @cfg {String} path The path for which the cookie is active (defaults to root '/' which makes it active for all pages in the site)
+ * @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')
+ * @cfg {Boolean} secure True if the site is using SSL (defaults to false)
+ * @constructor
+ * Create a new CookieProvider
+ * @param {Object} config The configuration object
