A system for preventing timeout of a client interface accessing a main Java Servlet executing in a first thread which monitors an application executing in a second thread. A task status object is accessed by the application to post its completion state and by the client interface responsive to a state refresh request to post a state refresh response including the completion state to the client. The state refresh response selectively includes a refresh attribute instructing the client to periodically post the state refresh request. Upon the application going to completion or error state, subsequent state refresh responses do not include the refresh attribute.
