-- | 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.
--
-- Contains the @Rules@ that identify the requests that you want to allow,
-- block, or count. In a @WebACL@, you also specify a default action
-- (@ALLOW@ or @BLOCK@), and the action for each @Rule@ that you add to a
-- @WebACL@, for example, block requests from specified IP addresses or
-- block requests from specified referrers. You also associate the @WebACL@
-- with a CloudFront distribution to identify the requests that you want
-- AWS WAF to filter. If you add more than one @Rule@ to a @WebACL@, a
-- request needs to match only one of the specifications to be allowed,
-- blocked, or counted. For more information, see UpdateWebACL.
