|
|
title: 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 URI<sup>[1](#ref-1)</sup> to one or more of the new
|
|
references sent by the server, where possible.
|
|
|
|
The server SHOULD generate a Location header field<sup>[2](#ref-2)</sup> 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 controls<sup>[3](#ref-3)</sup>.
|
|
|
|
Note: This status code is similar to [301 Moved
|
|
Permanently](/301), except that it does not allow changing the request method
|
|
from POST to GET.
