AWS WAF now supports ruleMatchDetails for Regex rules

AWS WAF has extended support of the ‘ruleMatchDetails’ field in the logs to include Regex rules. Customers use logs to further investigate the requests that are inspected by AWS WAF. The ‘ruleMatchDetails’ log field gives visibility into the part of a request that matched a rule or rule group. AWS WAF is a web application firewall that enables you to monitor the HTTP(S) requests that are made to your protected web application resources. By reviewing the ‘ruleMatchDetails’ log fields, customers can further investigate requests and tune their WAF accordingly, such as using ‘terminatingRuleMatchDetails’ or to determine whether a request was correctly blocked. AWS WAF previously only supported logging ‘ruleMatchDetails’ for SQLi and XSS rules. There is no additional cost for using this feature, but standard service charges for AWS WAF still apply. See the [AWS WAF Pricing](https://aws.amazon.com/waf/pricing/) page for more details. For more information about ruleMatchDetails for Regex Rules, visit the [Developer Guide](https://docs.aws.amazon.com/waf/latest/developerguide/logging-fields.html). This feature is available for all AWS Regions and for each supported service, including Amazon CloudFront, Amazon Application Load Balancer, Amazon API Gateway, AWS AppSync, and Amazon Cognito.
