The HTML server embedded within VTS can generate error responses under certain conditions. All error responses are generated using the standard HTML error reporting method, giving an error number and explanatory text. The explanatory text messages are defined in the [LABELS] section of Setup.ini and so may be customized if required (remember, in order to modify the values of variables in Setup.ini, you must restart VTS, not just your VTS application.) The [LABELS] section of Setup.ini is discussed in Setup.ini [LABELS] Section Variables.
