[users@httpd] X-Forwarded-For
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?

I thought each section has non-mod_cloudflare workarounds - I see only some
do.
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).

The X-Forwarded-For header is set by Apache automatically (
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#x-headers). Your inside
servers need to know to use it. CloudFlare has some documentation about how
to handle this on different servers:
