This article lists standard and notable non-standard HTTP response status codes. Standardized codes are defined by IETF as documented in Request for Comments (RFC) publications and maintained by the IANA. Other, non-standard values are used by various servers. The descriptive text after the numeric code – the reason phrase – is shown here with typical value, but in practice, can be different or omitted.
