We tried that. The proxy did not seem to "hand off" the connection.
Instead for each connection there was one process running in the proxy and 
another on the actual machine doing the actual serving.

So if we had
Machine A as proxy.

Machine B doing work

Machine C doing work.

We saw that if 500 connections came to B and 500 to C... there would be 1000 
connections on A.

Is that how it's supposed to work or perhaps we didn't configure it 
properly?
