Example Log output for a CAPTCHA rule against a web request with a valid, unexpired CAPTCHA token
The following log listing is for a web request that matched a rule with
CAPTCHA action. The web request has a valid and unexpired
CAPTCHA token, and is only noted as a CAPTCHA
match by AWS WAF, similar to the behavior for the Count action. This CAPTCHA
match is noted under nonTerminatingMatchingRules.
