// Associates a web ACL with a regional application resource, to protect the
// resource. A regional application can be an Application Load Balancer (ALB), an
// Amazon API Gateway REST API, an AppSync GraphQL API, an Amazon Cognito user
// pool, an App Runner service, or an Amazon Web Services Verified Access instance.
// For Amazon CloudFront, don't use this call. Instead, use your CloudFront
// distribution configuration. To associate a web ACL, in the CloudFront call
// UpdateDistribution , set the web ACL ID to the Amazon Resource Name (ARN) of the
// web ACL. For information, see UpdateDistribution (https://docs.aws.amazon.com/cloudfront/latest/APIReference/API_UpdateDistribution.html)
// in the Amazon CloudFront Developer Guide. When you make changes to web ACLs or
// web ACL components, like rules and rule groups, WAF propagates the changes
// everywhere that the web ACL and its components are stored and used. Your changes
// are applied within seconds, but there might be a brief period of inconsistency
// when the changes have arrived in some places and not in others. So, for example,
// if you change a rule action setting, the action might be the old action in one
// area and the new action in another area. Or if you add an IP address to an IP
// set used in a blocking rule, the new address might briefly be blocked in one
// area while still allowed in another. This temporary inconsistency can occur when
// you first associate a web ACL with an Amazon Web Services resource and when you
// change a web ACL that is already associated with a resource. Generally, any
// inconsistencies of this type last only a few seconds.
