RegexMatchSet

PDF
Note

AWS WAF Classic support will end on September 30, 2025.

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

In a GetRegexMatchSet request, RegexMatchSet is a complex type that contains the RegexMatchSetId and Name of a RegexMatchSet, and the values that you specified when you updated the RegexMatchSet.

The values are contained in a RegexMatchTuple object, which specify the parts of web requests that you want AWS WAF to inspect and the values that you want AWS WAF to search for. If a RegexMatchSet contains more than one RegexMatchTuple object, a request needs to match the settings in only one ByteMatchTuple to be considered a match.

Contents

Name

A friendly name or description of the RegexMatchSet. You can't change Name after you create a RegexMatchSet.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: .*\S.*

Required: No

RegexMatchSetId

The RegexMatchSetId for a RegexMatchSet. You use RegexMatchSetId to get information about a RegexMatchSet (see GetRegexMatchSet), update a RegexMatchSet (see UpdateRegexMatchSet), insert a RegexMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete a RegexMatchSet from AWS WAF (see DeleteRegexMatchSet).

RegexMatchSetId is returned by CreateRegexMatchSet and by ListRegexMatchSets.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: .*\S.*

Required: No

RegexMatchTuples

Contains an array of RegexMatchTuple objects. Each RegexMatchTuple object contains:

  • 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 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.

Type: Array of RegexMatchTuple objects
