Here's a cleaned up version of the same rule. See if this one runs any smoother.


when RULE_INIT {
  set error_404 "
Sorry, but the page you requested could not be found.
Please check that the requested page was typed properly and try again."
  set Servers_down "
Sorry, Servers are currently down for maintenance. Please check back in 10 minutes."
}
when HTTP_RESPONSE {
  if {[active_members [LB::server pool]] == 0} {
    HTTP::respond 200 content $::Servers_down
  } else {
    if { [HTTP::status] == 404 } {
      HTTP::respond 200 content $::error_404
    } elseif { [HTTP::status] >= 500 } {
        HTTP::respond 200 content $::Servers_down
    }
  }
}
