Hello F5workuserguy.

Try this:

when HTTP_REQUEST {
  if { [active_members [LB::server pool]] < 1 } {
    HTTP::respond 302 noserver Location "https://maintenance.google.com"
  }
}
 
when HTTP_RESPONSE {
  if { [HTTP::status] == "404" } {
    HTTP::respond 302 noserver Location "https://maintenance.google.com"
  }
}

Regards,

Dario.
