  You can't.  "if" is a processing directive that is valid only when
packets are being processed.  The configuration items are parsed once
when the server starts, and don't change after that.

  It would be very nice to be able to do that, but it would also be very
difficult to implement.  The solution is to add a layer of indirection:

  authorize_reply_query = "%{control:Tmp-String-0}"

  Then, while processing the request, set:

	update control {
		Tmp-String-0 = "..."
	}

  That *should* work, I think.
