One license consumed per browser: All applications started from the same browser count as one for licensing purposes, and therefore only one license is used.	See Genero front-ends and license counting
The `EXECUTION` element has an optional attribute, `CloseAllOnMainExit`. This allows you to specify that all child applications are closed gracefully when the user exits the main application.	See EXECUTION (under APPLICATION for JGAS)
`HEADER` elements specific to an application or service can be defined in the `HTTP` element of the configuration for application or service.	See: HEADER (Dedicated) HTTP (Dedicated) Configure application headers
