// This is AWS WAF Classic documentation. For more information, see AWS WAF Classic
// (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API
// and see the AWS WAF Developer Guide
// (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html). With
// the latest version, AWS WAF has a single set of endpoints for regional and
// global use. Inserts or deletes Predicate objects in a rule and updates the
// RateLimit in the rule. Each Predicate object identifies a predicate, such as a
// ByteMatchSet or an IPSet, that specifies the web requests that you want to block
// or count. The RateLimit specifies the number of requests every five minutes that
// triggers the rule. If you add more than one predicate to a RateBasedRule, a
// request must match all the predicates and exceed the RateLimit to be counted or
// blocked. For example, suppose you add the following to a RateBasedRule:
//
// * An
// IPSet that matches the IP address 192.0.2.44/32
//
// * A ByteMatchSet that matches
// BadBot in the User-Agent header
//
// Further, you specify a RateLimit of 1,000. You
// then add the RateBasedRule to a WebACL and specify that you want to block
// requests that satisfy the rule. For a request to be blocked, it must come from
// the IP address 192.0.2.44 and the User-Agent header in the request must contain
// the value BadBot. Further, requests that match these two conditions much be
// received at a rate of more than 1,000 every five minutes. If the rate drops
// below this limit, AWS WAF no longer blocks the requests. As a second example,
// suppose you want to limit requests to a particular page on your site. To do
// this, you could add the following to a RateBasedRule:
//
// * A ByteMatchSet with
// FieldToMatch of URI
//
// * A PositionalConstraint of STARTS_WITH
//
// * A TargetString
// of login
//
// Further, you specify a RateLimit of 1,000. By adding this
// RateBasedRule to a WebACL, you could limit requests to your login page without
// affecting the rest of your site.
