table 1 states that headers are not allowed in the R-URI:


                                                      dialog
                                         reg./redir. Contact/
             default  Req.-URI  To  From  Contact   R-R/Route  external
headers       --          -      -    -       o          -         o

also note 19.1.1:

  Elements processing URIs SHOULD ignore any disallowed components if
  they are present.

so, per 4475 3.1.2.11:

  It is acceptable for an element to reject this request with a 400 Bad
  Request.  An element could choose to be liberal in what it accepts
  and ignore the escaped headers.  If the element is a proxy, the
  escaped headers must not appear in the Request-URI of the forwarded
  request (and most certainly must not be translated into the actual
  header of the forwarded request).
