HTTP 202 Accepted vs 203 Non-Authoritative Information
Both HTTP 202 (Accepted) and 203 (Non-Authoritative Information) belong to the 2xx Success category. 202 indicates that the request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon. Meanwhile, 203 means that the response payload has been modified by a transforming proxy from the origin server's 200 response.
