Using a runtime configuration variable CGI-NO-CACHE, you can choose whether or not the HTML output of your CGI program will be cached by the requesting client. By default, the runtime generates "Pragma: no-cache" in the HTTP response header that gets sent to the standard output stream. If you set CGI-NO-CACHE to "0" (OFF, FALSE, NO) in the runtime configuration file, the runtime suppresses this line of the response header. The default value is "1" (ON, TRUE, YES).
