// Updates the specified WebACL . While updating a web ACL, WAF provides continuous
// coverage to the resources that you have associated with the web ACL. This
// operation completely replaces the mutable specifications that you already have
// for the web ACL with the ones that you provide to this call. To modify a web
// ACL, do the following:
//   - Retrieve it by calling GetWebACL
//   - Update its settings as needed
//   - Provide the complete web ACL specification to this call
//
// A web ACL defines a collection of rules to use to inspect and control web
// requests. Each rule has a statement that defines what to look for in web
// requests and an action that WAF applies to requests that match the statement. 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 Amazon Web Services resources to protect.
// The resources can be an Amazon CloudFront distribution, an Amazon API Gateway
// REST API, an Application Load Balancer, an AppSync GraphQL API, an Amazon
// Cognito user pool, an App Runner service, or an Amazon Web Services Verified
// Access instance. Temporary inconsistencies during updates When you create or
// change a web ACL or other WAF resources, the changes take a small amount of time
// to propagate to all areas where the resources are stored. The propagation time
// can be from a few seconds to a number of minutes. The following are examples of
// the temporary inconsistencies that you might notice during change propagation:
//   - After you create a web ACL, if you try to associate it with a resource, you
//     might get an exception indicating that the web ACL is unavailable.
//   - After you add a rule group to a web ACL, the new rule group rules might be
//     in effect in one area where the web ACL is used and not in another.
//   - After you change a rule action setting, you might see the old action in
//     some places and the new action in others.
//   - After you add an IP address to an IP set that is in use in a blocking rule,
//     the new address might be blocked in one area while still allowed in another.

	// The unique identifier for the web ACL. This ID is returned in the responses to
	// create and list commands. You provide it to operations like update and delete.
	//
	// This member is required.
	Id *string

	// A token used for optimistic locking. WAF returns a token to your get and list
	// requests, to mark the state of the entity at the time of the request. To make
	// changes to the entity associated with the token, you provide the token to
	// operations like update and delete . WAF uses the token to ensure that no changes
	// have been made to the entity since you last retrieved it. If a change has been
	// made, the update fails with a WAFOptimisticLockException . If this happens,
	// perform another get , and use the new token returned by that operation.
	//
	// This member is required.
	LockToken *string

	// The name of the web ACL. You cannot change the name of a web ACL after you
	// create it.
	//
	// This member is required.
	Name *string

	// Specifies whether this is for an Amazon CloudFront distribution or for a
	// regional application. 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. To work with CloudFront, you must also specify the Region US East (N.
	// Virginia) as follows:
	//   - CLI - Specify the Region when you use the CloudFront scope:
	//   --scope=CLOUDFRONT --region=us-east-1 .
	//   - API and SDKs - For all calls, use the Region endpoint us-east-1.
	//
	// This member is required.
	Scope types.Scope

	// Defines and enables Amazon CloudWatch metrics and web request sample collection.
	//
	// This member is required.
	VisibilityConfig *types.VisibilityConfig

	// Specifies custom configurations for the associations between the web ACL and
	// protected resources. Use this to customize the maximum size of the request body
	// that your protected CloudFront distributions forward to WAF for inspection. The
	// default is 16 KB (16,384 bytes). You are charged additional fees when your
	// protected resources forward body sizes that are larger than the default. For
	// more information, see WAF Pricing (http://aws.amazon.com/waf/pricing/) .
	AssociationConfig *types.AssociationConfig

	// Specifies how WAF should handle CAPTCHA evaluations for rules that don't have
	// their own CaptchaConfig settings. If you don't specify this, WAF uses its
	// default settings for CaptchaConfig .
	CaptchaConfig *types.CaptchaConfig

	// Specifies how WAF should handle challenge evaluations for rules that don't have
	// their own ChallengeConfig settings. If you don't specify this, WAF uses its
	// default settings for ChallengeConfig .
	ChallengeConfig *types.ChallengeConfig

	// A map of custom response keys and content bodies. When you create a rule with a
	// block action, you can send a custom response to the web request. You define
	// these for the web ACL, and then use them in the rules and default actions that
	// you define in the web ACL. For information about customizing web requests and
	// responses, see Customizing web requests and responses in WAF (https://docs.aws.amazon.com/waf/latest/developerguide/waf-custom-request-response.html)
	// in the WAF Developer Guide. For information about the limits on count and size
	// for custom request and response settings, see WAF quotas (https://docs.aws.amazon.com/waf/latest/developerguide/limits.html)
	// in the WAF Developer Guide.
	CustomResponseBodies map[string]types.CustomResponseBody

	// A description of the web ACL that helps with identification.
	Description *string

	// The Rule statements used to identify the web requests that you want to manage.
	// Each rule includes one top-level statement that WAF uses to identify matching
	// web requests, and parameters that govern how WAF handles them.
	Rules []types.Rule

	// Specifies the domains that WAF should accept in a web request token. This
	// enables the use of tokens across multiple protected websites. When WAF provides
	// a token, it uses the domain of the Amazon Web Services resource that the web ACL
	// is protecting. If you don't specify a list of token domains, WAF accepts tokens
	// only for the domain of the protected resource. With a token domain list, WAF
	// accepts the resource's host domain plus all domains in the token domain list,
	// including their prefixed subdomains. Example JSON: "TokenDomains": {
	// "mywebsite.com", "myotherwebsite.com" } Public suffixes aren't allowed. For
	// example, you can't use usa.gov or co.uk as token domains.
