How to use one HAProxy server for multiple domain

I have the below-mentioned scenario:

I have two domains let's say domain D1 & domain D2

Machines I have :

Machine M1LB that is for Load Balancer (HA Proxy)

Machine D1M1 & D1M2, that is for Application 1

Machine D2M1 & D2M2, that is for Application 2

Traffic of domain D1 should go on D1M1 & D1M2 machines with Load Balancer M1LB, Similarly for domain D2 should go on D2M1 & D2M2 machines.

Now, what is the best way to configure Load balancer with the help of only 1 machine?

Define two backends, and route by domain in frontend like this:

frontend http-in
        bind *:80

        acl host_d1 hdr(host) -i d1.com
        acl host_d2 hdr(host) -i d2.com

        use_backend be_d1 if host_d1
        use_backend be_d2 if host_d2

backend be_d1
        server D1M1 10.0.0.1:8080 
        server D1M2 10.0.0.2:8080 

backend be_d2
        server D2M1 10.0.0.1:8080 
        server D2M2 10.0.0.2:8080
