- What is named as flow token in Outbound, seems to be the value for
'alias' or 'received'. It can be an opaque value hiding these attributes in an internal storage or just set there in a specific format. The solutions we have now came based on needs, before outbound rfc was released (2009 vs path module in 2006).
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.
But I think we should update to standard param names, if they are defined now by IETF.
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.
