// TBD : do we have to set limits to the number of cookies at all?

// Possible answer : as we store cookies in an RPointerArray that has a

// restriction on the number of elements (max. 640 can be stored in an RArray

// or RPointerArray), we have to bother with it.

// TODO :

//	- change this value
