// UpdateByteMatchSetRequest returns a request value for making API operation for
// AWS WAF.
//
// Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet. For
// each ByteMatchTuple object, you specify the following values:
//
//    * Whether to insert or delete the object from the array. If you want to
//    change a ByteMatchSetUpdate object, you delete the existing object and
//    add a new one.
//
//    * The part of a web request that you want AWS WAF to inspect, such as
//    a query string or the value of the User-Agent header.
//
//    * The bytes (typically a string that corresponds with ASCII characters)
//    that you want AWS WAF to look for. For more information, including how
//    you specify the values for the AWS WAF API and the AWS CLI or SDKs, see
//    TargetString in the ByteMatchTuple data type.
//
//    * Where to look, such as at the beginning or the end of a query string.
//
//    * 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 add a ByteMatchSetUpdate object that matches web requests
// in which User-Agent headers contain the string BadBot. You can then configure
// AWS WAF to block those requests.
//
// To create and configure a ByteMatchSet, perform the following steps:
//
// Create a ByteMatchSet. For more information, see CreateByteMatchSet.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateByteMatchSet request.
//
// 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 AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/).
