Persistent Object

This script provides a mechanism for persisting Javascript objects between requests. A supertype object is defined which can be easily subclasseed (using Prototype) to create simple Active-record-like objects which can be saved, reloaded on a future request and deleted. Persistence is provided using a JSON-encoded cookie backend (similar to the existing Cookie Jar extension). The properties of an object are serialised and stored in a cookie identified by a key. Of course, due to the limitations associated with cookies, this isn't going to be suitable for all Javascript applications; however, the persistence provided is certainly useful. All feedback welcome.
