HTTP 203 Non-Authoritative Information vs 507 Insufficient Storage

HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 507 (Insufficient Storage) 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, 507 means that the server is unable to store the representation needed to complete the request (WebDAV).
