The HTTP 301
Moved Permanently
redirect status response code indicates that the resource requested has been definitively moved to the URL given by the Location
headers. A browser redirects to this page, and search engines update their links to the resource (In SEO-speak, it is said that the link-juice is sent to the new URL).
Even if the specification requires the method, and the body, not to be altered when the redirection is performed, not all user-agents align with it, and you can still find buggy software out there. It is therefore recommended to the 301
code only as a response for GET
or HEAD
methods and to use the 308
Permanent Redirect
instead, as the method change is explicitly prohibited with this status.
