- * @class Ext.state.CookieProvider
- * @extends Ext.state.Provider
- * The default Provider implementation which saves state via cookies.
- * <br />Usage:
- <pre><code>
- 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);
- </code></pre>
- * @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
