HTTP 203 Non-Authoritative Information vs 425 Too Early

HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 425 (Too Early) is a 4xx Client Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 425 means that the server is unwilling to risk processing a request that might be replayed. Used with TLS 1.3 early data (0-RTT).

설명

The response payload has been modified by a transforming proxy from the origin server's 200 response.

이 코드를 보게 되는 경우

When a proxy or CDN modifies the response body (e.g., adds headers, transforms content).

해결 방법

Check if a proxy is modifying the response. Access the origin directly if you need the original content.

이 코드를 보게 되는 경우

When a server rejects a request sent as TLS 1.3 early data due to replay risk.

해결 방법

Retry the request after the TLS handshake completes.
