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 Amazon WAF, similar to the behavior for the Count action. This CAPTCHA match is noted under nonTerminatingMatchingRules.
