If you want to serve additional pages using $DRIVER_INSTANCE_NAME$, place them in the DRIVER_HTML_ROOT directory. To serve a different home page than this one, replace the index.html file in that directory.
Additional HTTP servers can be created and managed by pointing your web browser to the 2001 port of your iSeries. You will need to make sure the *ADMIN Server is started.
To learn more, please refer to the list of documentation available on the HTTP Server for iSeries documentation page.
