iRule suggestion request

Hi,

We have two F5 Load balancers, those are internal and external. The request is to create a new VIP on external F5 with URL *.example.com(With external DNS entry) and for this VIP pool member will be the VIP in internal load balancer i.e *.example.abc.in.(With internal DNS entry)

So we require a iRule for the external VIP so that we can pass the traffic to the VIP in internal load balancer by replacing the domain name in host of the header.

For Example :

Incoming target: *.example.com

Rewrite to: *.example.abc.in

Thanks,
