Nginx wildcard proxy, pass subdomain to the server (upstream proxy)

I would like to be able to pass subdomain.domain.com to .domain.com apache server, with subdomain info too.

I would like to make a nginx cache for domain, acting like wildcard, but passing subdomain to the destination (there is apache witch wildcard too). Up to now, I pass the info via proxy_set_header Host $host; but I would like to have request with subdomain at the apache server.

  upstream domain.com {
    server 172.1.1.1:80 weight=50 fail_timeout=30s;
  }

  server {
    server_name *.domain.com;

    location / {
      proxy_pass http://domain.com;
      #proxy_pass $request;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $host;
     }

    location ~* ^.+.    (jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf)$ {
     proxy_pass http://topmanagergame.com;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_cache my-cache;
     proxy_cache_valid  200 302  30m;
     proxy_cache_valid  404      1m;
    }

    access_log /var/log/nginx/domain.com.log main;
    error_log off;
 }

Do you think I can use proxy_pass with upstream ?

Nginx (*wildcard_domain.com) --(cache)--> Apache (*wildcard_domain.com)
Nginx (anything.domain.com) --(cache)--> Apache (anything.domain.com)

So I was trying to find the answer to this problem and kept finding this post. But I think dmytrivv answer is out of date. In our scenario, we have both wildcard domains (e.g. *.mydomain.com) and custom domains (e.g. fullycustomdomain.com). But you can solve both by using proxy_set_header Host $host; and having default at the end of your listen.

upstream qaweb {
    # Servers in the web farm
    server ip-notreal-name.ec2.internal:80;
}


server {
        listen 443 ssl default;

        ssl_certificate     certs/mydomain.com.crt;
        ssl_certificate_key certs/mydomain.com.key;

        # Support for wildcard domains
        server_name admin.mydomain.com *.mydomain.com "";

        location / {
                # Turn off access logging so we don't fill the hardrive
                access_log      off;
                proxy_pass http://qaweb;
                proxy_set_header Host $host;
                # So that the correct IP shows up in the log once libapache2-mod-rpaf is installed
                proxy_set_header X-Real-IP  $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

Note, we are also using it as a TLS termination proxy.

upstream somestring {
    server domain2.com:80 weight=50 fail_timeout=30s;
}

server {
    listen  80;
    server_name *.domain.com;

    server_name ~^(?<subdomain>.+)\.domain\.com$;

    location / {
        proxy_pass http://somestring;
        proxy_set_header   Host             $subdomain.domain2.com;
    }
}
