Abstract
A method of controlling the existence of a Java object associated with a Web page in order to reuse the object, rather than create a new one when the Web page is revisited. The invention provides a method for allowing an object to register with a persistence manager upon creation, which maintains objects registered with it while the Web page is no longer being viewed. A Web browser translates instructions to create a Web page and invokes any Java objects resident on the page. The objects then check with the persistence manager to determine if the objects are present in the persistence manager. The objects in the persistence manager are then used, rather than creating new objects. The object remains registered until such time as it no longer needs to persist or until the Web browser is completely shut down.
