Reverse proxy - several virtual host - same proxy pass ip - getting wrong content

Hi

I am using nginx as reverse proxy and i have several names pointing to
reverse proxy and i am using proxy cache. My backends are basic LAMP
servers and IBM Lotus Domino servers.

Just wondering whats wrong as i changed domain to point my new nginx
server and i am getting wrong content, i am getting wrong virtual host
index page.

eg. i am trying to http://www.silverice.org/ and i am getting content
from
http://www.etappi.com/ they reside same LAMP-server. Looking my nginx
configuration i cant find anything wrong.
both named points to new nginx reverse proxy server. nginx version
0.7.65

Here is example from my config:

my main config, main parts:
------------8<--------------------------------
http {
proxy_cache_path /usr/share/nginx/cache levels=1:2
keys_zone=one:10m
max_size=1G;
proxy_temp_path /usr/share/nginx/tmp;

log_format main '$remote_addr - $remote_user [$time_local] $request

'"$status" $body_bytes_sent “$http_referer” ’
‘"$http_user_agent" “$http_x_forwarded_for”’;

proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;

default virtual host

server {
    listen          80 default;
    server_name     _;

    access_log  /var/log/nginx/default-access.log  main;

    server_name_in_redirect  off;

    location / {
        index index.html;
        root  /var/www/default/htdocs;
    }

}

here resides my virtual host configurations

include /etc/nginx/virtual-hosts/*;

}

and my virtual hosts under: /etc/nginx/virtual-hosts -directory:

they all look like this:
www.silverice.org:
--------------------------8<----------------

redirect silverice.org -> www.silverice.org

server {
server_name silverice.org;
rewrite ^/(.*)$ http://www.silverice.org/$1 permanent;
}

server {
server_name www.silverice.org;
access_log
/somedirectory/www.silverice.org/www.silverice.org-access_log combined;
default_type text/html;
root /usr/share/nginx/huolto;

location / {

  proxy_pass http://ip.add.re.ss;

  # manual maintenance window
  include /etc/nginx/maintenance.conf;

}

custom errorpages

include /etc/nginx/errorpages.conf;

general block rules, security rules, etc

include /etc/nginx/suojaus.conf;
}
-----------------------------8<------------------
And other virtual host like www.etappi.com looks like that, except name
and access log changed.

How come when trying to load www.silverice.org i am getting
www.etappi.com
content, mainly index page comes from wrong site.

Looking backend logs i cant find error there, nothing has changed there,
name based virtual host there, Apache v2.

you need to set a cache key based on the hostname (or something
dynamic) else you will serve caches content as (index.HTML) from site1
for site2 and site3… index requests
