<p>Hi andrew. Thanks for your help. What module or config should I use to make sure the connection goes back through the loadbalancer?</p>
<p>For the failover I didnt specify anything ping related. Im using the dispatcher module. Can I specify the ping config in that module or should I use another module for that?</p>
