     1152         the user agent to a selected resource, since doing so provides the information corresponding to the POST response in a form

     1157         that the follow-on representation may be useful without implying that that it adequately represents the previously requested
     1158         resource. Note that answers to the questions of what can be represented, what representations are adequate, and what might
     1159         be a useful description are outside the scope of HTTP and thus entirely determined by the resource owner(s).
