An HTTP status code is a three-digit number a server returns to tell the client how a request went. The first digit sets the class: 1xx informational, 2xx success, 3xx redirection, 4xx client error and 5xx server error. This page lists the common codes with their standard reason phrase and a short plain-language meaning.
