Allow/Disallow legacy screens
SCREEN and NOSCREEN are parameters on JANUS DEFINE, which defines and sets characteristics of a Janus port.
Indicates whether or not Janus Web Legacy screens will be allowed to appear on requests to the port. SCREEN, the default, specifies that Janus Web Legacy Support automatically renders any 3270 screen presented by an application as part of a Janus Web Legacy session. While this is convenient, it might be viewed as a security risk — 3270 screens not intended for web user consumption might accidentally appear on a browser because of an application error. To avoid this risk, specifying NOSCREEN on the port definition ensures that an attempt to display a 3270 screen on a web request will result in a user restart.
You can override the SCREEN and NOSCREEN parameters on the JANUS DEFINE command on a URL basis using the like-named parameters in JANUS WEB ON rules.
Valid only for WEBSERV ports.
