ProxySG Content Policy Language Guide
178
exception( )Selects a built-in or user-defined response to be returned to the user.
The exception( ) property is overridden by allow or deny( ). To set an exception that cannot be
overridden by allow, use force_exception( ).
The identity of the exception being returned can be tested in an <Exception> layer using
exception.id=.
Note: When the exception response selected would have a Content-Length of 512 or fewer bytes,
Internet Explorer may substitute “friendly” error messages. To prevent this behaviour use
exception.autopad(yes).

•details—A text string that is substituted for $(exception.details) within the selected
