I have set up NGINX as a load balancer for two Domino servers this way:
http {
upstream www.mydomain.com {
server 1.1.1.1;
server 2.2.2.2 backup;
}
server {
listen 80;
server_name www.mydomain.com;
location / {
proxy_pass http://www.mydomain.com;
}
}
}
If I access the Domino server directly the response headers are these:
HTTP/1.1 200 OK
Server: Lotus-Domino
Date: Mon, 23 Dec 2013 12:19:36 GMT
Last-Modified: Fri, 20 Dec 2013 08:16:27 GMT

When I access the same page via NGINX the response headers are these:
HTTP/1.1 200 OK
Server: nginx/1.0.15
Date: Mon, 23 Dec 2013 12:02:29 GMT
Content-Type: text/html; charset=US-ASCII

Can I configure NGINX to pass the response headers exactly as I get them directly from Domino? I know I can set some of these one by one like this:
proxy_pass_header Server;
But for example ETag
will not be passed even this way.
