Visual DataFlex Web Application Servers execute Web-based application software developed with Visual DataFlex Studio. Web Application Server’s components include the application execution engine, a COM-based interface to Microsoft’s Internet Information Services (IIS), database utilities, the embedded database and, optionally, database connectivity drivers. A Visual DataFlex Web Application Server license is required for each hardware server on which a VDF web application is installed.
