Re: X-Forwarded-For (Apache Users)

The Apache documentation for mod_proxy has a suggestion for changing the format of the log file (can paste a link from this device, but it should e easy enough to find) to also include the header, but if you want to replace the client IP, you will need some kind of module or code change (there are others besides the cloudflare one).

Thanks Yehuda! Cloudflare wants you to install its mod. Is it possible to use what i already have to do this, which is apache?

Apache 2.2 (i believe) on sles11. We have some servers behind our apache (reverse) proxy. When connections come in to apache and apache proxies the connections, the logs show the apache proxy ip. We need to see the originating ip. I have seen on the internet that x-forwarded-for will do this. Can anyone provide some config doc or guidance for x-forwarded-for?
