You get a response to the request you made.  It may not be the response
that some applications of HTTP will be looking for, ultimately, but
that is outside the scope of HTTP.

Anyway, this is dancing around the point.  It is false to say that a
303 response implies that the URI identifies a resource that is not an
information resource.  All it implies is what the 303 says -- if you
want information about this resource in the form of a representation,
then look over there.  We don't need to speculate any further about
the resource that has not been represented.
