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
: IPSet
that matches the IP address 192.0.2.44/32
ByteMatchSet
that matches BadBot
in the User-Agent
header 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
: ByteMatchSet
with FieldToMatch
of URI
PositionalConstraint
of STARTS_WITH
TargetString
of login
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. Required? | True |
