Forward to virtual and APM

Hi,

I'm trying to define a Virtual Server as a Load-Balancer between multiple VS

Load-balancing is based on hostname

when HTTP_REQUEST {
        if {[HTTP::host] contains "test.mydom.com" } {
                log local0. "Site Test 1"
                virtual /Common/vs_test.mydom.com
        } elseif {[HTTP::host] contains "test2.mydom.com" } {
                log local0. "Site Test 2"
                virtual /Common/vs_test2.mydom.com
        } else {
                log local0. "SiteA"
        }
}

Everything is working fine except that APM inside vs_test1 & vs_test2 are not applied

I'm able to connect to these VS without authentication

Is there any limitation or is it by-design?

Thank you

Nicolas
