Maint page irule help

Update to f5_rock’s updated iRule to remove duplication, also you don’t need the else and pool http_80 lines if you are using the default pool assigned to the virtual server.

when HTTP_REQUEST {
     Pool members is less than 0 or client IP is not in subnet 10.0.0.0/8 return maintenance page
    if {[active_members [LB::server pool]] < 1 || [IP::addr [IP::client_addr]/8 ne 10.0.0.0]} {
        HTTP::respond 200 content [ifile get "Maintenance_html"] noserver "Cache-Control"   "no-store, no-cache"
    } else {
        pool http_80
    } 
}
