I'm going to go out on a limb here and say that you can't(Or shouldn't just in case somehow you can...), first, for me at least, it would boggle the mind that you have a reverse proxy using a forward proxy.
I guess you could use a transparent proxy although I'm still not sure why but HAproxy would then just be routing to it's destination unaware there's a proxy in the way... However, the question really has to be why? Only thing I can think of is that you are trying to implement a DMZ so have decided to restrict all outbound traffic, why not just allow the specific traffic through the firewall? You can cherry pick exactly what to allow so only allow the destination or sources that you actually require, it would be much much easier. Sorry if that's not what you wanted to hear or if I'm wrong in some way...
