+If no <em>status</em> argument is given, the redirect will be
+"temporary" (HTTP status 302). This indicates to the client that the
+resources is has moved temporarily. The <em>status</em>
+argument can be used to return other HTTP status codes:
+<dl>
+<dt>permanent<dd>Returns a permanent redirect status (301) indicating that
+the resource has moved permanently.
+<dt>temp<dd>Returns a temporary redirect status (302). This is the
+default.
+<dt>seeother<dd>Returns a "See Other" status (303) indicating that
+the resource has been replaced.
+<dt>gone<dd>Returns a "Gone" status (410) indicating that the resource
+has been permanently removed. When this status is used the <em>url</em>
+argument should be omitted.
+</dl>
+
+Other status codes can be returned by giving the numeric status code
+as the value of <em>status</em>. If the status is between 300 and 399,
+the <em>url</em> argument must be present, otherwise it must be
+omitted. Note that the status must be known to the Apache code (see
+the function <code>send_error_response</code> in http_protocol.c).
