recommend using a 301 redirect to change the URL of a page as it is shown in search engine results, providing that the URL will permanently change and is not due to be changed again any time soon.
870:: The new URL should always be provided in the "Location" field when a 301 redirect is sent. Omitting the Location header will confuse browsers and may result in unexpected behavior.

908:: Using multiple 301 redirects in succession (A to B, then B to C) can lead to increased page load times and may dilute SEO value.
857:: Used when the result of a POST or another non-idempotent request method is a resource that should be retrieved using a GET.

Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URL(s).
