The 303 (See Other) status code indicates that the server is redirecting the
user agent to a different resource, as indicated by a URI in the Location header
field, which is intended to provide an indirect response to the original
request. A user agent can perform a retrieval request targeting that URI (a GET
or HEAD request if using HTTP), which might also be redirected, and present the
eventual result as an answer to the original request. Note that the new URI in
the Location header field is not considered equivalent to the effective request
URI.

This status code is applicable to any HTTP method. It is primarily used to allow
the output of a POST action to redirect the user agent to a selected resource,
since doing so provides the information corresponding to the POST response in a
form that can be separately identified, bookmarked, and cached, independent of
the original request.

A 303 response to a GET request indicates that the origin server does not have a
representation of the target resource that can be transferred by the server over
HTTP. However, the Location field value refers to a resource that is descriptive
of the target resource, such that making a retrieval request on that other
resource might result in a representation that is useful to recipients without
implying that it represents the original target resource. Note that answers to
the questions of what can be represented, what representations are adequate, and
what might be a useful description are outside the scope of HTTP.

Except for responses to a HEAD request, the representation of a 303 response
ought to contain a short hypertext note with a hyperlink to the same URI
reference provided in the Location header field.
