Thanks!  Thats exactly what I needed.

Just wondering on these lines though:

>       proxy_set_header  X-Real-IP  $remote_addr;
>       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;

on my system, i use this:

	proxy_set_header Host $host;
	proxy_set_header X-Forwarded-For $remote_addr;

which is where i go off into a tangent-

	isn't it bad form / dangerous to rely on x-forwarded-for from the  
client for anything?
	shouldn't you force it to be $remote_addr ( it defaults to that if  
there is no x-forwarded-for header ) in almost any situation ?
