Questions tagged [http-status-codes]

HTTP status codes are a set of standardized codes returned in an HTTP web response. Questions about why a service is (unexpectedly) returning a status code should not use this tag.

For a full list of the status codes see the HTTP 1.1 specification, WebDAV specification, RFC 6585, and the IANA list of status codes.

HTTP status codes have specific meanings which are outlined in the specification that they were created in. They can be used in contexts outside of what the specification states, but must adhere to any conditions that have been established in the specification.
