// This is AWS WAF Classic documentation. For more information, see AWS WAF Classic (https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html)
// in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API
// and see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html)
// . 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:
//   - 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/)
// .
