Hi Joe,

for sure is this doable (almost everything is possible with F5 BIG-IP and iRules).

Not sure where you have the [HTTP::name] from, as this is not a valid command, but your requirement should be solved with this iRule:

when HTTP_REQUEST {
    if { [active_members [LB::server pool]] < 1 } {
        set subdomain [substr [HTTP::host] 0 "."]
        HTTP::redirect "https://redirect.newdomain.com/$subdomain/more/stuff"
    }
}

Please give it a try and let me know if this is fine for you.

Ciao Stefan 🙂
