SetEnv can't do that. SetEnvIf might be able to (with a suitable change in syntax -- see the docs), or you could use mod_rewrite. But why are you bothering? Your application should be able to directly access X-Forwarded-For. (Also, careful using X-Forwarded-For because it could contain more than one IP address in the case of a chain of proxies.) Joshua.I did try to use X-Forwarded-For directly. But I did not get any value there.Anand
I finally managed to get the client IP. I had to use mod_proxy_add_forward.c and
mod_rpaf ....X-Forwarded-For header was not getting set. So I had to use mod_proxy_add_forward.c . Once that header got set, my app was not able to use it directly. As I had written earlier, my app can see only CGI vars...So then had to use mod_rpaf to move X-Forwarded-For into Remote IP.
