iRule to set recursion on DNS request

Hi guys, Wondered if anyone had experience of or knows of a resource online for how to set the recursion flag on a DNS request? I'm forwarding the DNS request based on domain with another iRule but...

Incase anyone is interested I managed to get an iRule working for this;

when DNS_REQUEST {
  if { [DNS::header rd] eq "0" } {
    DNS::header rd 1
  }
}

Cheers
