Not exactly, sorry, the proxy should forward the CANCEL stateless:

16.10 CANCEL Processing
   [...]
   If a response context is not found, the element does not have any
   knowledge of the request to apply the CANCEL to.  It MUST statelessly
   forward the CANCEL request (it may have statelessly forwarded the
   associated request previously).
