흔히 이렇게 알고 있다
Calling ClientIPFromXFF with no arguments extracts the originating client IP from the leftmost entry in X-Forwarded-For and updates RemoteAddr like RealIP.
이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.
컨트랙트
- assert ClientIPFromXFF with unset trusted prefixes returns the rightmost XFF hop rather than the leftmost client IP
- assert ClientIPFromXFF leaves RemoteAddr unmodified and stores the resolved IP in context
- assert ClientIPFromXFF with explicit trusted CIDR prefixes skips trusted hops to extract the originating client IP
- assert ClientIPFromXFF fails closed returning an empty IP when encountering an invalid hop in the chain
- assert ClientIPFromXFF merges multiple X-Forwarded-For headers and evaluates hops right to left
