I would use a background process that does the work and adds the items to a database table. The index function would periodically refresh or pull an updated list via ajax from the database table. there is no way for te server to trigger an action in the browser unless 1) the browser initiates it or 2) the client code embeds an ajax http server. I would stay away from 1 and 2 and use reload of ajax.
