// UpdateWebACLRequest returns a request value for making API operation for
// AWS WAF Regional.
//
// 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 CreateRule and UpdateRule.
//
// Create a WebACL. See CreateWebACL.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateWebACL request.
//
// 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 UpdateWebACL request 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 (https://docs.aws.amazon.com/waf/latest/developerguide/).
