 | -- Its easy to reuse this load balancer module with these protocols.
 | --   ps (send a pull request if your desired protocol is not here).
 | --
 | -- The first section is for the application (layer 7) load balancer 
 | -- which only handles HTTP/HTTPS traffic that almost always originates
 | -- from human beings. The second section configures machine traffic
 | -- handled by the (layer 4) network load balancer.
 | --
 | --
 | -- Example - Human traffic from port 80 to RabbitMQ UI port 15672
 | --           (application load balancer)
 | --
 | --    in_front_end = [ "http"    ]
 | --    in_back_end  = [ "rabbit" ]
 | --
 | --
 | -- Example - Machine AMQP (tcp) traffic from/to port 5672
 | --           (network load balancer)
 | --
 | --    in_front_end = [ "http"    ]
 | --    in_back_end  = [ "rabbit" ]
