CGI User Interface

The Gateway applet does not have, and in fact, does not need, much of a user interface to be functional. Since it merely relays data from point to point, it only needs the URL of the server program and specifications for its input and output.
With the UserInterface HTML parameter, the application developer can control which of three UI configurations the applet uses. The full user interface includes a text label for the server URL, Submit and Cancel buttons, and a status message area. The Button user interface contains only the Submit button. In both of these cases, data is sent to the server only after the user presses the Submit button. None indicates the applet should not show a user interface; if this option is chosen, data is sent to the server as soon as it is all collected.
