F5 LTM request logging via different route domain

Hi!

Have you tried this irule? : 

when CLIENT_ACCEPTED {
  set my_hsl [HSL::open -publisher /<partition>/<log publisher>]
}
when HTTP_REQUEST {
  HSL::send $my_hsl "Request: [HTTP::host][HTTP::uri]"
  log local0.info "Request: [HTTP::host][HTTP::uri]"
}
when CLIENT_CLOSED {
  unset my_hsl
}

I found this here:
