The concept is that BackhandProxied will *only* be set on the machined that is
being proxied to. Unfortunately, my code doesn't reflect that concept :-( A
one line patch fixes this -- it is in CVS and attached at the bottom of this
message. If the header exists at all, you know it was backhanded to you.
Otherwise, it originated from the client.
So you want something like this:
SetEnvIf BackhandProxied . bh
CustomLog /var/backhand/logs/frontend_access_log funky env=!bh
CustomLog /var/backhand/logs/backend_access_log funky env=bh
