BOTDEFENSE::cs_possible
       Returns whether it is possible for Bot Defense to take a client-side
       action.

SYNOPSIS
       BOTDEFENSE::cs_possible

DESCRIPTION
       Returns "true" or "false" based on whether it is possible to take one
       of the client-side actions (browser challenge, or CAPTCHA challenge).
       Certain characteristics of a request makes it impossible to respond
       with a browser or CAPTCHA challenge, in which case "false" is returned.

       Setting to a client-side action with BOTDEFENSE::action, while the
       value of BOTDEFENSE::cs_possible is "false", will fail.

       Syntax

       BOTDEFENSE::cs_possible

RETURN VALUE
       Returns a boolean value (0 or 1), whether taking a client-side action
       is possible.

VALID DURING
       BOTDEFENSE_REQUEST, BOTDEFENSE_ACTION

	# EXAMPLE: Prevent blocking of requests that cannot be responded with a
	# client-side challenge.
