Rule, which contains the
objects, and other predicates that identify the requests that you want to block. If
you add more than one predicate to a
Rule, a request must match all of
the specifications to be allowed or blocked. For example, suppose you add the following
IPSet that matches the IP address
ByteMatchSet that matches
BadBot in the
You then add the
Rule to a
WebACL and specify that you want
to blocks requests that satisfy the
Rule. For a request to be blocked,
it must come from the IP address 192.0.2.44 and the
header in the request must contain the value
To create and configure a
Rule, perform the following steps:
Use GetChangeToken to get the change token that you provide in the
parameter of a
GetChangeToken to get the change token that you provide in the
parameter of an UpdateRule request.
UpdateRule request to specify the predicates that you want
to include in the
Create and update a
WebACL that contains the
Rule. For more

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateRule and EndCreateRule.
public abstract Task<CreateRuleResponse> CreateRuleAsync( String name, String changeToken, String metricName, CancellationToken cancellationToken )
A friendly name or description of the Rule. You can't change the name of a Rule after you create it.
The value returned by the most recent call to GetChangeToken.
A friendly name or description for the metrics for this Rule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9); the name can't contain whitespace. You can't change the name of the metric after you create the Rule.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
|WAFDisallowedNameException||The name specified is invalid.|
|WAFInternalErrorException||The operation failed because of a system problem, even though the request was valid. Retry your request.|
|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 DefaultActionType 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 WafActionType other than ALLOW, BLOCK, or COUNT. You tried to update a ByteMatchSet with a FieldToMatchType other than HEADER, QUERY_STRING, or URI. 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.|
|WAFStaleDataException||The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.|
