HTTP 203 Non-Authoritative Information vs 506 Variant Also Negotiates
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 506 (Variant Also Negotiates) is a 5xx Server Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 506 means that the server has an internal configuration error: the chosen variant resource is configured to engage in content negotiation itself.
