-- 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 RegexMatchTuple objects (filters) in a RegexMatchSet.
-- For each @RegexMatchSetUpdate@ object, you specify the following values:
--
-- -   Whether to insert or delete the object from the array. If you want
--     to change a @RegexMatchSetUpdate@ object, you delete the existing
--     object and add a new one.
--
-- -   The part of a web request that you want AWS WAF to inspectupdate,
--     such as a query string or the value of the @User-Agent@ header.
--
-- -   The identifier of the pattern (a regular expression) that you want
--     AWS WAF to look for. For more information, see RegexPatternSet.
--
-- -   Whether to perform any conversions on the request, such as
--     converting it to lowercase, before inspecting it for the specified
--     string.
--
-- For example, you can create a @RegexPatternSet@ that matches any
-- requests with @User-Agent@ headers that contain the string
-- @B[a\@]dB[o0]t@. You can then configure AWS WAF to reject those
-- requests.
--
-- To create and configure a @RegexMatchSet@, perform the following steps:
--
-- 1.  Create a @RegexMatchSet.@ For more information, see
--     CreateRegexMatchSet.
--
-- 2.  Use GetChangeToken to get the change token that you provide in the
--     @ChangeToken@ parameter of an @UpdateRegexMatchSet@ request.
--
-- 3.  Submit an @UpdateRegexMatchSet@ request to specify the part of the
--     request that you want AWS WAF to inspect (for example, the header or
--     the URI) and the identifier of the @RegexPatternSet@ that contain
--     the regular expression patters 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>.
