Hi Rahul,
I don't understand your example. In that case, you are always using
"10.97.116.36"
as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru.
This will of course lead to 1 call being reported always, since
request-URIs tend to be different from each other.
Regards,
Carlos
