	I thought docs are very helpful at most of time. :p

	So.. the core concept of *originate-coa* is just "proxy-the-coa"
instead of initiating a coa request?

	Hmm..that is indeed an alternative, but like you said, it's kind of
not a neat way to achieve my goal.
	And I'm worrying that might have some performance issue if supposed
I will have high traffic.

	No offense, I'm curious that why can't view these two request:
"Proxy-Auth Request" and "CoA Request" as two independent request?
	Or this is about some kind of concern on designation? I thought that
was intuitive until I saw the result and got your kind but hopeless response

	Ok. I got your point.

	What do you mean *after*? The next any-kind-of request?
	But I really need they do it in the same sequence. It a bit upset
me.

	Thanks Alan! Thanks your contribution and devotion to FreeRADIUS. 
	It's really impressive. Not a compliment at all. lol
