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.
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 address192.0.2.44/32
- A
ByteMatchSet
that matchesBadBot
in theUser-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
withFieldToMatch
ofURI
- A
PositionalConstraint
ofSTARTS_WITH
- A
TargetString
oflogin
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.

Create a value of UpdateRateBasedRule
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:ruleId:UpdateRateBasedRule'
, updateRateBasedRule_ruleId
- The RuleId
of the RateBasedRule
that you want to update. RuleId
is
returned by CreateRateBasedRule
and by ListRateBasedRules.
$sel:changeToken:UpdateRateBasedRule'
, updateRateBasedRule_changeToken
- The value returned by the most recent call to GetChangeToken.
$sel:updates:UpdateRateBasedRule'
, updateRateBasedRule_updates
- An array of RuleUpdate
objects that you want to insert into or delete
from a RateBasedRule.
$sel:rateLimit:UpdateRateBasedRule'
, updateRateBasedRule_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.
Request Lenses
