The capchas should be one use only, otherwise an attacker can send several times the same form with the same captcha once it is solved. Optionally, a parameter is added to continue with the previous behaviour.
Delete value of the anti CSRF in the session so it can be created again, making it of one use only, preventing an attacker to send the same form several times.
