haproxy doesn't care where the backends are, it just uses whatever backend you have depending on your rules.

You can use the url matching functions in haproxy to tell it which backend to use depending on the incoming requested url.

What have you tried so far?

TenTenths, sir what if the balancer DOWN or connection down (is there a configuration can i do in the servers(site webs) to works without the balancer)? or i should add another balancer or what?

Here we use 2 haproxy servers with keepalived for a shared IP address.

TenTenths, sir!, what if i wana separate the 2 Haproxy servers (not in the same place, every Hproxy srv in a place(eg: 1st Hproxy srv in NewYork, 2end Hproxy in LA)+(i need theme to be connected) like master and slave, i'm looking for High Availability sir, so in this case is that possible to configure the two HaProxy servers?
and thank you sir, for you replays

You can have as many haproxy servers as you like, they have front-end listeners that they pass to the back-end servers. With keepalived they can share a front-end IP address. How and where you put them is up to you and depends on how your internal network is designed.
