/**
|
* 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: "/cgi-bin/",
|
* expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
|
* domain: "sencha.com"
|
* });
|
*
|
* Ext.state.Manager.setProvider(cp);
|
*
