Disable VIP when pool members are down

Hi Is is possible with iRules to send reset flag to client when health monitor fails on all pool members. We don't want f5 to accept any traffic.   Thanks

Please find below an example for HTTP (HTTP_REQUEST) and another generic (LB_FAILED) : 

when CLIENT_ACCEPTED {
    set default_pool [LB::server pool]
}

when HTTP_REQUEST {
    set method [HTTP::method]
    if { [active_members $default_pool] < 1 } { 
        HTTP::respond 200 content [ifile get "/Common/maintenance.html"] noserver "Content-Type" "text/html" "Cache-Control" "no-cache, must-revalidate" 
         reject 
    }
}

when LB_FAILED { 
  reject
}
