// CreateSizeConstraintSetRequest returns a request value for making API operation for
// AWS WAF.
//
// 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:
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of a CreateSizeConstraintSet request.
//
// Submit a CreateSizeConstraintSet request.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateSizeConstraintSet request.
//
// 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 (https://docs.aws.amazon.com/waf/latest/developerguide/).
