Setup for reverse proxy

Follow the steps below

1. Setup an upstream block within the http block

2. nginx configuration

   http

   {
       upstream my_glassfish_cluster 

       {
           server backend1.example.com weight=5;
           server 192.168.99.100:28080;
           server 192.168.99.100:28081 backup;
       }
   }

3. Now specify the upstream group that nginx will pass requests to (can be any one of the following protocols: proxy_pass, fastcgi_pass, memcached_pass, uwsgi_pass, or scgi_pass)

4. nginx configuration

   http

   {

      ...

      server 

      {
         location / 

         {
            proxy_pass http://my_glassfish_cluster;
         }

      }
   }

   This will pass all http requests up to my_glassfish_cluster server group
