-- Creates a 'ByteMatchSet'. You then use UpdateByteMatchSet to identify
-- the part of a web request that you want AWS WAF to inspect, such as the
-- values of the 'User-Agent' header or the query string. For example, you
-- can create a 'ByteMatchSet' that matches any requests with 'User-Agent'
-- headers that contain the string 'BadBot'. You can then configure AWS WAF
-- to reject those requests.
--
-- To create and configure a 'ByteMatchSet', perform the following steps:
--
-- 1.  Use GetChangeToken to get the change token that you provide in the
--     'ChangeToken' parameter of a 'CreateByteMatchSet' request.
-- 2.  Submit a 'CreateByteMatchSet' request.
-- 3.  Use 'GetChangeToken' to get the change token that you provide in the
--     'ChangeToken' parameter of an 'UpdateByteMatchSet' request.
-- 4.  Submit an UpdateByteMatchSet 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
