#text_transformation ⇒ String
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 performs the transformation on
FieldToMatch
before inspecting it for a match.
You can only specify a single type of TextTransformation.
CMD_LINE
