// Package wafv2 provides the API client, operations, and parameter types for AWS
// WAFV2.
//
// WAF This is the latest version of the WAF API, released in November, 2019. The
// names of the entities that you use to access this API, like endpoints and
// namespaces, all have the versioning information added, like "V2" or "v2", to
// distinguish from the prior version. We recommend migrating your resources to
// this version, because it has a number of significant improvements. If you used
// WAF prior to this release, you can't use this WAFV2 API to access any WAF
// resources that you created before. You can access your old rules, web ACLs, and
// other WAF resources only through the WAF Classic APIs. The WAF Classic APIs have
// retained the prior names, endpoints, and namespaces. For information, including
// how to migrate your WAF resources to this version, see the WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . WAF is a web application firewall that lets you monitor the HTTP and HTTPS
// requests that are forwarded to an Amazon CloudFront distribution, Amazon API
// Gateway REST API, Application Load Balancer, AppSync GraphQL API, Amazon Cognito
// user pool, App Runner service, or Amazon Web Services Verified Access instance.
// WAF also lets you control access to your content, to protect the Amazon Web
// Services resource that WAF is monitoring. Based on conditions that you specify,
// such as the IP addresses that requests originate from or the values of query
// strings, the protected resource responds to requests with either the requested
// content, an HTTP 403 status code (Forbidden), or with a custom response. This
// API guide is for developers who need detailed information about WAF API actions,
// data types, and errors. For detailed information about WAF features and guidance
// for configuring and using WAF, see the WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/what-is-aws-waf.html)
// . You can make calls using the endpoints listed in WAF endpoints and quotas (https://docs.aws.amazon.com/general/latest/gr/waf.html)
// .
//   - For regional applications, you can use any of the endpoints in the list. 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 applications, you must use the API endpoint listed
//     for US East (N. Virginia): us-east-1.
//
// Alternatively, you can use one of the Amazon Web Services SDKs to access an API
// that's tailored to the programming language or platform that you're using. For
// more information, see Amazon Web Services SDKs (http://aws.amazon.com/tools/#SDKs)
// . We currently provide two versions of the WAF API: this API and the prior
// versions, the classic WAF APIs. This new API provides the same functionality as
// the older versions, with the following major improvements:
//   - You use one API for both global and regional applications. Where you need
//     to distinguish the scope, you specify a Scope parameter and set it to
//     CLOUDFRONT or REGIONAL .
//   - You can define a web ACL or rule group with a single call, and update it
//     with a single call. You define all rule specifications in JSON format, and pass
//     them to your rule group or web ACL calls.
//   - The limits WAF places on the use of rules more closely reflects the cost of
//     running each type of rule. Rule groups include capacity settings, so you know
//     the maximum cost of a rule group when you use it.
