AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

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.

Creates a SizeConstraintSet. You then use UpdateSizeConstraintSet to identify the part of a web request that you want AWS WAF to check for length, such as the length of the User-Agent header or the length of the query string. For example, you can create a SizeConstraintSet that matches any requests that have a query string that is longer than 100 bytes. You can then configure AWS WAF to reject those requests.

To create and configure a SizeConstraintSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateSizeConstraintSet request.

  2. Submit a CreateSizeConstraintSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.

  4. Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Note:

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 BeginCreateSizeConstraintSet and EndCreateSizeConstraintSet.

Exceptions

ExceptionCondition
WAFDisallowedNameException The name specified is invalid.
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.
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, 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.
WAFStaleDataException The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.
