The detection of a triggering event needs to initiate a set of predefined actions which in most cases will require that the Web Server get control of a computer or terminal at one or more sites in order to display messages or get more information.

• Set up mechanisms that will reverse the normal flow of the server just responding to the browser, so that the server will be able to request the browser's attention and send it a file. This control will be necessary whenever a triggering event takes place. We will have to compare overall performance of keeping the socket to the Browser open, versus giving the Browser instructions to reload the document in a specified interval so we will know when that time is expired we will again have an open socket.
• Develop Java Applets that are needed to facilitate requests for data entry and to allow users to filter, reorder or combine action lists.
