HTTP 203 Non-Authoritative Information vs 407 Proxy Authentication Required
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 407 (Proxy Authentication Required) 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, 407 means that the client must first authenticate itself with the proxy.
