I think he's trying to say he feels it's a web server problem not a load 
balance problem. Surely what you want is a simple web redirect.

What's more confusing is //ipApplication is a URL so it would go to that 
machine. So basically I don't think you are asking quite the correct question.

Maybe I missunderstood the terminology, sorry. I wanted to say cluster nodes 
instead of realserver. Isn't it LVS? 
(I thougth ldirectord managed the ipvsadm commands when the ldirectord.conf is 
something like this
virtual=xx.xx.xx.xx:80
        real=xx.xx.xx.x1:80 masq 1 ".healthcheck.html", "OK"
        real=xx.xx.xx.x2:80 masq 1 ".healthcheck.html", "OK"
        real=xx.xx.xx.x3:80 masq 1 ".healthcheck.html", "OK"
        real=xx.xx.xx.x4:80 masq 1 ".healthcheck.html", "OK"
        service=http
        checkport=80
        protocol=tcp
        scheduler=wrr
        checktype=negotiate
        fallback=127.0.0.1:80
Isn't it LVS? Maybe I don't know what I'm talking about.
Thanks in advance!
