|
The 301 Moved Permanently status code indicates that 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 to one or more of the new references sent by the
|
|
server, where possible.
|
|
|
|
The server SHOULD generate a Location header field 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).
|
|
|
|
Note: For historical reasons, a user agent MAY change the request method from
|
|
POST to GET for the subsequent request. If this behavior is undesired, the
|
|
[307 (Temporary Redirect)](/307) status code can be used instead.
|
|
|
|
A 301 response is cacheable by default; i.e., unless otherwise indicated by the
|
|
method definition or explicit cache controls
|
|
(see [Section 4.2.2 of [RFC7234]][2]).
