in the past, I've done this:

	Proxy in:
		strip all x-* headers
		insert x-forwarded-for / x-real-ip info
		insert x-internal-passkey , which is just a simple string that is  
known only to proxy and backend apps.  this gives a little more  
assurance to the backend app that the request came through the  
expected proxy server
	Proxy out:
		strip all x-* headers

would that be difficult to do in nginx ?
