HTTP 203 Non-Authoritative Information vs 403 Forbidden
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 403 (Forbidden) 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, 403 means that the server understood the request but refuses to authorize it. Unlike 401, authentication will not help — the user simply does not have permission.
