Creates a
WebACL, which contains the
Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates
Rules in order based on the value of
Priority for each
Rule.
You also specify a default action, either ALLOW or BLOCK. If a web request doesn't match any of the Rules in a WebACL, AWS WAF responds to the request with the default action.
To create and configure a WebACL, perform the following steps:
-
Create and update the ByteMatchSet objects and other predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
-
Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.
-
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateWebACL request.
-
Submit a CreateWebACL request.
-
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.
-
Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.
For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide.

///
/// 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,

///
/// -
///
/// You tried to create a
WebACL with a DefaultAction Type
/// other than ALLOW, BLOCK, or COUNT.
///
/// -
///
/// 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, QUERY_STRING, or URI.
///
/// -
///
/// You tried to update a
ByteMatchSet with a Field of HEADER

///
/// -
///
/// Your request references an ARN that is malformed, or corresponds to a resource with
/// which a web ACL cannot be associated.
///
///
///
/// 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.
///
/// The operation failed because you tried to create, update, or delete an object by using
