#text_transformations ⇒ AWSCDK::IResolvable, Array<AWSCDK::IResolvable, AWSCDK::WAFv2::CfnWebACL::TextTransformationProperty> (readonly)

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

Returns:
