Duplicate Log entries using mod_backhand

Hello,

I have a cluster that I want to use MLS on but I am having difficulty
getting it to only log a request once. My backhand setup is a single tier so
the Apache servicing the request also proxies to and from other machines.

I have tried to get the request to be logged from the machine that is the
proxy for this request, but I cannot seem to prevent the servicing machine
from also logging it through spread.

Any machine in the cluster may be a proxy or a backend machine at any time.

I found an email from George on Google, but it did not help. You can see the
portion of http.conf below. I commented out my
attempts to try George's, but still not go.

Can anyone give me an idea if how to do this?

Thanks,

Dennis
