RFC 5626 has an example algorithm (section 5.2.) for generating the flow
token from these values. It basically, just adds a hash using a key that
is re-generated upon proxy restart essentially adding an epoch to the
token.

The RFC suggest to stuff the token into the userpart of the
Path/Record-Route URI. Since that one is unused anyhow, seems like a
good idea.
