302 Found and 307 Temporary Redirect

A HTTP 302 or HTTP 307 response given in response to a HTTP request means that the requested resource resides temporarily under a different URL. The client should continue to use the request URL in future, since the redirection may be altered on occasion.

The temporary URL should be given by the Location field in the HTTP 301 response. In addition, the entity of the response should contain a short hypertext note with a hyperlink to the new URL (unless the request method was HEAD).

A search engine that receives a HTTP 302 or HTTP 307 response upon requesting a given URL is likely to:

index the content found at the Location field, under the URL given in the requested URL, rather than the Location field (assuming that both are on the same site!)
pass link rank weight from the page containing the link to the requested URL, to the page given in the Location field
