// This is AWS WAF Classic documentation. For more information, see [AWS WAF Classic] in the
// developer guide.
//
// For the latest version of AWS WAF, use the AWS WAFV2 API and see the [AWS WAF Developer Guide]. With the
// latest version, AWS WAF has a single set of endpoints for regional and global
// use.
//
// Inserts or deletes ActivatedRule objects in a WebACL . Each Rule identifies web requests
// that you want to allow, block, or count. When you update a WebACL , you specify
// the following values:
//
//   - A default action for the WebACL , either ALLOW or BLOCK . AWS WAF performs
//     the default action if a request doesn't match the criteria in any of the Rules
//     in a WebACL .
//
//   - The Rules that you want to add or delete. If you want to replace one Rule
//     with another, you delete the existing Rule and add the new one.
//
//   - For each Rule , whether you want AWS WAF to allow requests, block requests,
//     or count requests that match the conditions in the Rule .
//
//   - The order in which you want AWS WAF to evaluate the Rules in a WebACL . If
//     you add more than one Rule to a WebACL , AWS WAF evaluates each request
//     against the Rules in order based on the value of Priority . (The Rule that has
//     the lowest value for Priority is evaluated first.) When a web request matches
//     all the predicates (such as ByteMatchSets and IPSets ) in a Rule , AWS WAF
//     immediately takes the corresponding action, allow or block, and doesn't evaluate
//     the request against the remaining Rules in the WebACL , if any.
//
// To create and configure a WebACL , perform the following steps:
//
//   - Create and update the predicates that you want to include in Rules . For
//     more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
//
//   - Create and update the Rules that you want to include in the WebACL . For
//     more information, see CreateRuleand UpdateRule.
//
//   - Create a WebACL . See CreateWebACL.
//
//   - Use GetChangeToken to get the change token that you provide in the
//     ChangeToken parameter of an UpdateWebACLrequest.
//
//   - Submit an UpdateWebACL request to specify the Rules that you want to include
//     in the WebACL , to specify the default action, and to associate the WebACL
//     with a CloudFront distribution.
//
// The ActivatedRule can be a rule group. If you specify a rule group as your
//
//	ActivatedRule , you can exclude specific rules from that rule group.
//
// If you already have a rule group associated with a web ACL and want to submit
//
//	an UpdateWebACL request to exclude certain rules from that rule group, you
//	must first remove the rule group from the web ACL, the re-insert it again,
//	specifying the excluded rules. For details, see ActivatedRule$ExcludedRules.
//
// Be aware that if you try to add a RATE_BASED rule to a web ACL without setting
// the rule type when first creating the rule, the UpdateWebACLrequest will fail because the
// request tries to add a REGULAR rule (the default rule type) with the specified
// ID, which does not exist.
//
// For more information about how to use the AWS WAF API to allow or block HTTP
// requests, see the [AWS WAF Developer Guide].
