The configuration of a web-based terminal emulation session involves both the Reflection for the Web applet and the host session.
When you create a session, you determine its configuration settings using applet defaults, applet parameters, host system defaults, and a configuration file. (The applet parameters and configuration file are optional.) Users can then create their own user preference files to change some elements of the default configuration. The degree to which users can save their own configurations is itself part of the session configuration.
