Falling back to a disabled pool member, if all others are down?

Hi Erlend,

how about creating a "shadow pool" with same members and same monitors. Members in shadow pool will always remain in "enabled" state but may be marked by monitor as "down". An iRule will forward traffic to the shadow pool if all members of the default pool are "offline" or "disabled".

when LB_FAILED {
    pool pool_shadow
}

Or alternatively:

when CLIENT_ACCEPTED {
    if { [active_members pool_default] < 1 } {
        pool pool_shadow
    }
}

Thanks, Stephan
