Simple virtualhost setup that passes static files to nginx and everything else to Apache

nginx.conf

http {

  server {

    server_name ~^(.+)$;
    set $domain $1;
    root /var/www/dropbox/$domain;

    location / {
      proxy_pass http://127.0.0.1:8000;
      proxy_set_header Host $host;
    }

    location ~* "\.(jpg|jpeg|gif|css|png|js|ico|ttf|woff|eot|pdf|mov|mp3|aac|txt)$" {
      try_files $uri $uri/ /public/$uri /var/www/dropbox/$domain/public/$uri;

      access_log off;
      add_header Access-Control-Allow-Origin *;
      expires 30d;

    }

  }

}
