TextTransformation |
String
|
Required: Yes. Specifies how AWS WAF processes the FieldToMatch property before inspecting a request for a match. Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF transforms theFieldToMatch parameter before inspecting a web request for a match.For example, AWS WAF can replace white space characters (such as \t and \n) with a single space. For valid values, see the TextTransformation content for the XssMatchTuple data type in the AWS WAF API Reference. |
