IISProxy module configuration

Does anyone know what a typical EP 5.0 SP 5 IISProxy.xml file should contain? I'd like to upgrade from the ISAPI filter SAPJ2EE.dll/SAPJ2EE.ini version 1.2.5.0 to IISProxy.dll/IISProxy.xml 1.3.3.0 but I'm not sure of the parameter mappings.

Any suggestions or examples are greatly appreciated.
