Question

I have created a Play! Application which is working fine.
Eg:
I creted a login page when submitted it will take to a frontpage module’s loginCheck method which validates and redirect to a inner page.

I have 6 instances of play running in the machine.

I created Load Balancer Play application in another machine. Which will point to any one of the instance at a time. I want to use the Load Balancer for DB request and Web request too.

DB Request – It just updates the DB and ends there.

Web Request – It(LoadBalancer) has to send the request to the instance it will have a response which i will display in the web page through the LoadBalancer.

For Eg:
For the First web request will render the login page. so i send the request as web.
It will send to the instance and response (Login page) is returned. Which i am able to render.

My Problem is the login page form submit will take to frontpage module’s logincheck method which is not inside LoadBalancer Application. i wanted to send the page back to the instance with those post values through LoadBalancer how can i do that.

(Key -> Server = play )                 

         Request                                        Request                                                   Request

LB - Load Balancer

Answer 1

We created a LoadBalancer using netty which is a open library. works fine.
