How to specify which of the webservers to target?

Thanks for the reply, ill check out that property.
But this means the load balancer still decides which server to initially make a connection with. I am trying to cut out that decision and run my test suite on each server so i can potentially highlight any webservices issues on individual servers.
e.g test suite on server 1 failed but passed on 2 and 3. So i know there is an issue on server 1.
Does that make sense?
