no $HTTP_X_FORWARDED_FOR?!?

[moretar7]

Hi,

I'm trying to find the proxy & real ip of a client but the problem is that there's no $HTTP_X_FORWARDED_FOR variable, not even if I look in phpinfo().

I'm using PHP 4.0.4 pl 1.

When I use phpinfo() from another website on the net using PHP 4.2.2 it has the variable under the Apache Environment.

What can I do to access this variable?

Thanks.
