308 Permanent Redirect
The target resource has been assigned a new permanent URI and any future references to this resource ought to use one of the enclosed URIs.
Clients with link editing capabilities ought to automatically re-link references to the effective request URI1 to one or more of the new references sent by the server, where possible.
The server SHOULD generate a Location header field2 in the response containing a preferred URI reference for the new permanent URI. The user agent MAY use the Location field value for automatic redirection. The server's response payload usually contains a short hypertext note with a hyperlink to the new URI(s).
A 308 response is cacheable by default; i.e., unless otherwise indicated by the method definition or explicit cache controls3.
Note: This status code is similar to 301 Moved Permanently, except that it does not allow changing the request method from POST to GET.
