how to make HAproxy itself reply to a health check from another load balancer?

[Florin Andrei]

Let's say HAproxy is used for a second layer of load balancers, with the 
first layer being AWS ELBs.

When you create an ELB, you can specify a health check. This should 
actually check the health of the HAproxy instances that the ELB is 
pointing at.

Is there a way to make HAproxy answer a health check from an ELB? This 
health check cannot be passed all the way to the backend web servers, 
because they all answer different URL prefixes.
