</span> * A Provider implementation which saves and retrieves state via cookies. The CookieProvider supports the usual cookie
 * options, such as:
 *
 * - {@link #path}
 * - {@link #expires}
 * - {@link #domain}
 * - {@link #secure}
 *
 * Example:
 *
 *     var cp = Ext.create('Ext.state.CookieProvider', {
 *         path: &quot;/cgi-bin/&quot;,
 *         expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
 *         domain: &quot;sencha.com&quot;
 *     });
 *
 *     Ext.state.Manager.setProvider(cp);
