    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.

    A RateBasedRule is identical to a regular Rule, with one addition: a RateBasedRule counts the number of requests that arrive from a specified IP address every five minutes. For example, based on recent requests that you've seen from an attacker, you might create a RateBasedRule that includes the following conditions:

    • The requests come from 192.0.2.44.

    • They contain the value BadBot in the User-Agent header.

    In the rule, you also define the rate limit as 1,000.

    Requests that meet both of these conditions and exceed 1,000 requests every five minutes trigger the rule's action (block or count), which is defined in the web ACL.

    • Method Detail

      • ruleId

        public final String ruleId()

        A unique identifier for a RateBasedRule. You use RuleId to get more information about a RateBasedRule (see GetRateBasedRule), update a RateBasedRule (see UpdateRateBasedRule), insert a RateBasedRule into a WebACL or delete one from a WebACL (see UpdateWebACL), or delete a RateBasedRule from AWS WAF (see DeleteRateBasedRule).

        Returns:
        A unique identifier for a RateBasedRule. You use RuleId to get more information about a RateBasedRule (see GetRateBasedRule), update a RateBasedRule (see UpdateRateBasedRule), insert a RateBasedRule into a WebACL or delete one from a WebACL (see UpdateWebACL), or delete a RateBasedRule from AWS WAF (see DeleteRateBasedRule).

      • name

        public final String name()

        A friendly name or description for a RateBasedRule. You can't change the name of a RateBasedRule after you create it.

        Returns:
        A friendly name or description for a RateBasedRule. You can't change the name of a RateBasedRule after you create it.

      • metricName

        public final String metricName()

        A friendly name or description for the metrics for a RateBasedRule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change the name of the metric after you create the RateBasedRule.

        Returns:
        A friendly name or description for the metrics for a RateBasedRule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change the name of the metric after you create the RateBasedRule.

      • hasMatchPredicates

        public final boolean hasMatchPredicates()
        For responses, this returns true if the service returned a value for the MatchPredicates property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • matchPredicates

        public final List<Predicate> matchPredicates()

        The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet object that you want to include in a RateBasedRule.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasMatchPredicates() method.

        Returns:
        The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet object that you want to include in a RateBasedRule.

      • rateKey

        public final RateKey rateKey()

        The field that AWS WAF uses to determine if requests are likely arriving from single source and thus subject to rate monitoring. The only valid value for RateKey is IP. IP indicates that requests arriving from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

        If the service returns an enum value that is not available in the current SDK version, rateKey will return RateKey.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from rateKeyAsString().

        Returns:
        The field that AWS WAF uses to determine if requests are likely arriving from single source and thus subject to rate monitoring. The only valid value for RateKey is IP. IP indicates that requests arriving from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

      • rateKeyAsString

        public final String rateKeyAsString()

        The field that AWS WAF uses to determine if requests are likely arriving from single source and thus subject to rate monitoring. The only valid value for RateKey is IP. IP indicates that requests arriving from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

        If the service returns an enum value that is not available in the current SDK version, rateKey will return RateKey.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from rateKeyAsString().

        Returns:

IP indicates that requests arriving from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

      • rateLimit

        public final Long 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.

        Returns:
        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.
