// UpdateRegexMatchSetRequest returns a request value for making API operation for
// AWS WAF Regional.
//
// 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:
//
// Create a RegexMatchSet. For more information, see CreateRegexMatchSet.
//
// Use GetChangeToken to get the change token that you provide in the ChangeToken
// parameter of an UpdateRegexMatchSet request.
//
// 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 AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/).
