Log custom HTTP headers?

Our organization just deployed a web server running Domino 6.5.1 onRedHat Advanced Server 2.1. I have enabled access logging to files.

The server sits behind a piece of network equipment that listens on

our public IP on port 80 and passes HTTP traffic to the web server.

Unfortunately, a side effect of this is that the web server sees all

HTTP traffic as coming from the network hardware, and as such the only

IP address that gets logged in the access log is that of the network

hardware. Obviously this screws up our reports because it looks like

all of our site traffic is coming from one IP.

Our networking department has provided a workaround for this: they

are able to configure the hardware to insert a custom HTTP header

(“OrigClientAddr”) on all incoming HTTP requests that contains the IP

address of the client. This has worked out in the past with Apache

servers as I could use a LogFormat directive that included this header.

But I can’t figure out how to do this with Domino. Any clues?

Thanks,

Steve
