Modify, add, remove, or pass along specific response headers coming downstream from the origin.

Depending on the type of action you want to perform, specify the corresponding standard header name, or a customHeaderName if the standard name is set to OTHER. The headerValue serves as a match condition when the action is DELETE or MODIFY, and the newHeaderValue applies when the action is ADD or MODIFY.
