text Transformation
Parameters
value
Parameter is used to eliminate unusual formatting that attackers may use in web requests to bypass AWS WAF. When a transformation is specified, AWS WAF performs the transformation on the field_to_match
before inspecting the request for a match. Some examples of supported transformations are CMD_LINE
, HTML_ENTITY_DECODE
, and NONE
. You can find a complete list of supported values in the AWS WAF API Reference. Note: If you choose BODY
as the type
, you must also choose NONE
because CloudFront only forwards the first 8192 bytes for inspection.
