// This is AWS WAF Classic documentation. For more information, see AWS WAF Classic (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API
// and see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . With the latest version, AWS WAF has a single set of endpoints for regional
// and global use. Inserts or deletes SizeConstraint objects (filters) in a
// SizeConstraintSet . For each SizeConstraint object, you specify the following
// values:
// - Whether to insert or delete the object from the array. If you want to
// change a SizeConstraintSetUpdate object, you delete the existing object and
// add a new one.
// - The part of a web request that you want AWS WAF to evaluate, such as the
// length of a query string or the length of the User-Agent header.
// - Whether to perform any transformations on the request, such as converting
// it to lowercase, before checking its length. Note that transformations of the
// request body are not supported because the AWS resource forwards only the first
// 8192 bytes of your request to AWS WAF. You can only specify a single type of
// TextTransformation.
// - A ComparisonOperator used for evaluating the selected part of the request
// against the specified Size , such as equals, greater than, less than, and so
// on.
// - The length, in bytes, that you want AWS WAF to watch for in selected part
// of the request. The length is computed after applying the transformation.
//
// For example, you can add a SizeConstraintSetUpdate object that matches web
// requests in which the length of the User-Agent header is greater than 100
// bytes. You can then configure AWS WAF to block those requests. To create and
// configure a SizeConstraintSet , perform the following steps:
// - Create a SizeConstraintSet. For more information, see
// CreateSizeConstraintSet .
// - 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/)
// .
