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.
