// This is the latest version of AWS WAF, named AWS WAFV2, released in November,
// 2019. For information, including how to migrate your AWS WAF resources from
// the prior release, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
//
// Updates the specified WebACL.
//
// A Web ACL defines a collection of rules to use to inspect and control web
// requests. Each rule has an action defined (allow, block, or count) for requests
// that match the statement of the rule. In the Web ACL, you assign a default
// action to take (allow, block) for any request that does not match any of
// the rules. The rules in a Web ACL can be a combination of the types Rule,
// RuleGroup, and managed rule group. You can associate a Web ACL with one or
// more AWS resources to protect. The resources can be Amazon CloudFront, an
// Amazon API Gateway API, or an Application Load Balancer.
//
//    // Example sending a request using UpdateWebACLRequest.
//    req := client.UpdateWebACLRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
//    }
