-objects that are references by unique name's by the wxApplet. These
-values can be used to store and retrieve data that needs to remain
-persisent across invocations of the wxApplet. Ie: The first time an
-applet is created it would use the cookie to store data to maintain
-it's present state so that if you navigated back to the same page
-is would be able to re-load the prior state as though the applet
-was never actually destructed.
-

- false. Hence if you wish to replace a cookie you should first call
- UnRegisterCookie to ensure the cookie is deleted and then call this
