Re: [Sip] Comparison of retargeting proposals
It is clearly not the same as History-Info header as has been explained
in the draft and in several previous threads. It has also been explained
why History-Info can not be used for this as is.
A simple new header with a clear semantics which provides a clean
solution to the problem is therefore not even challenged by the
History-Info header. Instead you should argue why History-Info is so
bloody good that we should use it for this. We just learned that it is
not even usable as a diagnostic tool.
Why carry a whole log of request URI rewrites around when you are only
interested in the current target???

Any addition of a new header that nobody can explain properly why it's
not the same as History-Info IS rocket science.
It sounds like we are getting paid by the number of URI we add to SIP.
