-- This is __AWS WAF Classic__ documentation. For more information, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html AWS WAF Classic>
-- in the developer guide.
--
-- __For the latest version of AWS WAF__, use the AWS WAFV2 API and see the
-- <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html AWS WAF Developer Guide>.
-- 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:
--
-- 1.  Create a @SizeConstraintSet.@ For more information, see
--     CreateSizeConstraintSet.
--
-- 2.  Use GetChangeToken to get the change token that you provide in the
--     @ChangeToken@ parameter of an @UpdateSizeConstraintSet@ request.
--
-- 3.  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
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
