Does append_hf not work for CANCEL requests?
Correct: CANCEL is a "hop-by-hop" request where the proxy is a distinct
hop, i.e. UAC sends a CANCEL to the proxy, and the proxy sends a
separate CANCEL of its own on the branch that it initiated. This is in
contrast to something like a BYE, and most requests, which are
end-to-end request that the proxy simply relays upstream as received.
