How to setup 2 dispatchers in AEM local instance

Question

I've setup 2 publishers (4503 and 4504) and I've setup one dispatcher for 4503 via Apache HTTP web server. Now what I intend to do is setup another dispatcher for pub2 on 4504 and enable load balancing. Can anyone help me or provide me the instructions to accomplish this?

Hi @arindam6600

As far as I understand you are talking about the below setup. Please confirm

A multi-legged topology would have one Dispatcher per Publish server. A dedicated (hardware) load balancer sits in front of the AEM infrastructure dispatching the requests to these two (or more) legs:

For each Dispatcher, configure the dispatcher.any file with the appropriate settings. This file is typically located in the Apache HTTP Server's conf directory. Below is an example snippet of a Dispatcher configuration:

/clientheaders {
  ...
}

/renders {
  /rend01 {
    ...
    /farm {
      /publish {
        /localhost {
          "hostname" "publish-instance1"
          "port" "4503"
          ...
        }
        /localhost {
          "hostname" "publish-instance2"
          "port" "4503"
          ...
        }
        ...
      }
    }
  }
}

One dispatcher could potentially load balance both publish servers. Is there a specific use case that needs 2 dispatchers, one for each publish instance?
