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 address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-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 with FieldToMatch of URI

  • A PositionalConstraint of STARTS_WITH

  • A TargetString of login

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.

Parameters:

  • rule_id (ResourceId) –

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

  • change_token (ChangeToken) –

    The value returned by the most recent call to GetChangeToken.

  • updates (RuleUpdates) –

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

  • rate_limit (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.

Raises:

  • WAFInternalErrorException –

    The operation failed because of a system problem, even though the request was valid. Retry your request.

  • WAFInvalidAccountException –

    The operation failed because you tried to create, update, or delete an object by using an invalid account identifier.

  • WAFInvalidOperationException –

    The operation failed because there was nothing to do. For example:

    • You tried to remove a Rule from a WebACL, but the Rule isn't in the specified WebACL.

    • You tried to remove an IP address from an IPSet, but the IP address isn't in the specified IPSet.

    • You tried to remove a ByteMatchTuple from a ByteMatchSet, but the ByteMatchTuple isn't in the specified WebACL.

    • You tried to add a Rule to a WebACL, but the Rule already exists in the specified WebACL.

    • You tried to add a ByteMatchTuple to a ByteMatchSet, but the ByteMatchTuple already exists in the specified WebACL.

  • WAFInvalidParameterException –

    The operation failed because AWS WAF didn't recognize a parameter in the request. For example:

    • You specified an invalid parameter name.

    • You specified an invalid value.

    • You tried to update an object (ByteMatchSet, IPSet, Rule, or WebACL) using an action other than INSERT or DELETE.

    • You tried to create a WebACL with a DefaultAction Type other than ALLOW, BLOCK, or COUNT.

    • You tried to create a RateBasedRule with a RateKey value other than IP.

    • You tried to update a WebACL with a WafAction Type other than ALLOW, BLOCK, or COUNT.

    • You tried to update a ByteMatchSet with a FieldToMatch Type other than HEADER, METHOD, QUERY_STRING, URI, or BODY.

    • You tried to update a ByteMatchSet with a Field of HEADER but no value for Data.

    • Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.

  • WAFLimitsExceededException –

    The operation exceeds a resource limit, for example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see Limits in the AWS WAF Developer Guide.

  • WAFNonexistentContainerException –

    The operation failed because you tried to add an object to or delete an object from another object that doesn't exist. For example:

    • You tried to add a Rule to or delete a Rule from a WebACL that doesn't exist.

    • You tried to add a ByteMatchSet to or delete a ByteMatchSet from a Rule that doesn't exist.

    • You tried to add an IP address to or delete an IP address from an IPSet that doesn't exist.

    • You tried to add a ByteMatchTuple to or delete a ByteMatchTuple from a ByteMatchSet that doesn't exist.

  • WAFNonexistentItemException –

    The operation failed because the referenced object doesn't exist.

  • WAFReferencedItemException –

    The operation failed because you tried to delete an object that is still in use. For example:

    • You tried to delete a ByteMatchSet that is still referenced by a Rule.

    • You tried to delete a Rule that is still referenced by a WebACL.

  • WAFStaleDataException –

    The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.

  • UnknownServiceError –

    The service returned an error code this client does not model.
