ProxySG Content Policy Language Guide

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).
Syntax

•
exception_id—Either the name of a built-in exception (refer to Chapter 14: “Advanced Policy”
in the ProxySG Configuration and Management Guide for the list of built-in exceptions), or a name of
the form
user_defined.exception_id that refers to a user-defined exception page.
•
details—A text string that is substituted for $(exception.details) within the selected
exception.
