HTTP Load Balancing using Message Server

Hi Experts,

I am using a REST Web Service( Created in SICF ) to be consumed directly(using the URI) via external applications. We have Load Balancing configured in our landscape.

In the table RZLLITAB, the message server group is configured and is assigned to respective app servers.

Currently, we don't have a Web Dispatcher configured in our system, and i wanted to use the Message Server as a Load Balancer.

Since, REST Services are stateless, do i really need to install the Web Dispatcher in this case.?

Thanks

Sahil
