Nginx solution for Apache ProxyPassReverse

Let’s say we want to establish simple proxy between myhost:80 and myapp:8080. The Apache rule is simple:

APACHE

<VirtualHost myhost:80>
    ServerName myhost
    DocumentRoot /path/to/myapp/public
    ProxyPass / http://myapp:8080/
    ProxyPassReverse / http://myapp:8080/
</VirtualHost>

But Nginx does not have ProxyPassReverse…The solution is adding few missing HTTP headers.

Please also see http://wiki.nginx.org/HttpProxyModule#proxy_redirect , This wiki is partly incorrect. If you need to do location header rewriting. You will need to use proxy_redirect as well.
NGINX:

server {
  listen myhost:80;
  server_name  myhost;
  location / {
    root /path/to/myapp/public;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_pass http://myapp:8080;
  }
}
