/**
*
*
* This is the latest version of AWS WAF, named AWS WAFV2, released in November, 2019. For information, including
* how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide.
*
*
*
* A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the
* rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a
* temporary block on requests from an IP address that is sending excessive requests.
*
*
* When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls
* below the limit.
*
*
* You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it
* only counts requests that match the nested statement. For example, based on recent requests that you have seen from
* an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested
* statements:
*
*
* -
*
* An IP match statement with an IP set that specified the address 192.0.2.44.
*
*
* -
*
* A string match statement that searches in the User-Agent header for the string BadBot.
*
*
*
*
* In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet
* both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule
* action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not
* affected by this rule.
*
*
* You cannot nest a RateBasedStatement, for example for use inside a NotStatement or
* OrStatement. It can only be referenced as a top-level statement within a rule.
*
*
* @see AWS API
* Documentation
