Container for the parameters to the UpdateRateBasedRule operation. 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:

Further, you specify a RateLimit of 15,000.

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 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 15,000 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:

Further, you specify a RateLimit of 15,000.

By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

The UpdateRateBasedRuleRequest type exposes the following members



Public Property ChangeToken System.String

Gets and sets the property ChangeToken.

The value returned by the most recent call to GetChangeToken.

Public Property RateLimit System.Int64

Gets and sets the property RateLimit.

The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.

Public Property RuleId System.String

Gets and sets the property RuleId.

The RuleId of the RateBasedRule that you want to update. RuleId is returned by CreateRateBasedRule and by ListRateBasedRules.

Public Property Updates System.Collections.Generic.List<Amazon.WAF.Model.RuleUpdate>

Gets and sets the property Updates.

An array of RuleUpdate objects that you want to insert into or delete from a RateBasedRule.
