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.)
