textTransformations property
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.
