The HTTP response status code 301 Moved Permanently is used for permanent redirection.

This status code should be used with the location header. RFC 2616 states that:

  • If a client has link-editing capabilities, it should update all references to the Request URI.
  • The response is cachable.
  • Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URI(s).
  • If the 301 status code is received in response to a request of any type other than GET or HEAD, the client must ask the user before redirecting.

Example

Client request:

GET /index.php HTTP/1.1
Host: www.example.org

Server response:

HTTP/1.1 301 Moved Permanently
Location: http://www.example.org/login.php
