Apache Configuration Question

$_SERVER headers are missing in PHP but present in Python

I'm behind a transparent proxy which always adds the HTTP_X_FORWARDED_FOR header.

When I dump the headers out using PHP the header is missing. But Python works.. lol


remote_addr = os.environ.get('HTTP_X_FORWARDED_FOR', os.environ.get('REMOTE_ADDR', ''))



---- EDIT: Added more info on configs below ------

Hostgator does not support mod_python but I'm on a dedicated box, so I can modify the configs if I only knew how.. :)

You are using FastCGI. PHP isn't at ease with this, though it's making progress. With PHP 5.3 came php-fpm, with 5.4 will come HTTP headers for FastCGI. See the changelog of apache_request_headers or getAllHeaders().

Though there's no pure PHP solution, the first note of the previous link contains a workaround: using mod_rewrite to set up environment variables.
