Question

What’s the difference between a 302 FOUND and a 307 TEMPORARY REDIRECT HTTP response?

The W3 spec seems to indicate that they’re both used for temporary redirects, and neither can be cached unless the response specifically allows it.

Answer 1

The difference concerns redirecting POST, PUT and DELETE requests and what the expectations of the server are for the user agent behavior (RFC 2616):

Note: RFC 1945 and RFC 2068 specify that the client is not allowed to
change the method on the redirected
request. However, most existing user
agent implementations treat 302 as if
it were a 303 response, performing a
GET on the Location field-value
regardless of the original request
method. The status codes 303 and 307
have been added for servers that wish
to make unambiguously clear which kind
of reaction is expected of the
client.
