HTTP 203 Non-Authoritative Information vs 416 Range Not Satisfiable
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 416 (Range Not Satisfiable) 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, 416 means that the server cannot serve the requested byte range. The Range header value is outside the resource's size.
