ABSTRACT:
In an HTTP client-server system, an HTTP client requests an HTML document containing a persistent display element and using components available to the HTTP client for processing HTML documents, processes the requested HTML document including instantiating an instance of the persistent display element, whereby the persistent display element instance maintains a connection to an event source. When an event is received from the event source over the connection to the persistent display element instance, the received event is processed to form a change of at least a portion of a display of the HTTP client, which is displayed on the display of the HTTP client.
