As I understand it, 301 (moved permanently), 302 (found) and 307 (not
modified) all indicate a different location for the resource, never for
an alternative to it. 304 is "Not modified", and 305/6 are
deprecated/reserved respectively. So, I don't think there is any other
redirect code for "Instead of the resource you requested, please see
this resource instead"...
