    You can use something like this:

    When HTTP_REQUEST {
if { [active_members pool_name] < 1 } {
HTTP::respond 302 Location "http://domain.com/maintenance.html"
}
}

    There are multiple variations of this in devcentral. A search online should help. Also, fallback host in HTTP profile can also be used.

    Hi,

    You need to create 3 load balancing pools.

    1 pool that has a generic http monitor and is used for traffic processing.

    1 pool with a monitor with a disabled string 1 and pool name pool_1 (this pool won't process traffic)

    1 pool with a monitor with a disabled string 2 and pool name pool_2 (this pool won't process traffic)

    Your irule will look like:

    When HTTP_REQUEST {
    if { [active_members pool_1] < 1 } {
        HTTP::respond 302 Location "http://domain.com/maintenance_1.html"
    } elseif { [active_members pool_2] < 1 } {
        HTTP::respond 302 Location "http://domain.com/maintenance_1.html"
    }    
}

    Cheers,

    Kees
