301 Moved Permanently
The HTTP
301 Moved Permanently redirection response status code indicates that the requested resource has been permanently moved to the URL in the Location header.A browser receiving this status will automatically request the resource at the URL in the
Location header, redirecting the user to the new page.
Search engines receiving this response will attribute links to the original URL to the redirected resource, passing the SEO ranking to the new URL.Note:
In the Fetch Standard (external), when a user agent receives a
301 in response to a POST request, it uses the GET method in the subsequent redirection request, as permitted by the HTTP specification.
To avoid user agents modifying the request, use 308 Permanent Redirect instead, as altering the method after a 308 response is prohibited.Status
