ASM::captcha_age¶
Description¶
Returns the age of the CAPTCHA challenge in seconds, or -1 if not applicable.
Examples¶
# EXAMPLE: Send CAPTCHA challenge and validate the response, but to avoid
# blocking requests to which CAPTCHA challenge cannot be sent (non-HTML pages),
# send the CAPTCHA challenge on HTML pages after 30 seconds of aging, which is
# before the expiration of the answer.
