The HTTP 203 Non-Authoritative Information response status indicates that the request was successful but the enclosed payload has been modified by a transforming proxy from that of the origin server's 200 (OK) response .
The 203 response is similar to the value 214, meaning Transformation Applied, of the Warning header code, which has the additional advantage of being applicable to responses with any status code.
