CURL + HTTP_X_FORWARDED_FOR

[cyfer65]

how can I set the HTTP_X_FORWARDED_FOR header in a curl request so when I curl this site:http://dawhois.com/my_ip_address.phpmy real IP shows up for the "IP Behind Proxy" Section..?

Hi cyfer65,I recommend that you try the following:

curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue'));

as in:

curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-FORWARDED-FOR: 1.2.3.4'));

curl_setopt can probably be used to send headers: http://php.net/manual/en/function.curl-setopt.php

does that code work for you..?I try it and it still shows "IP Behind Proxy = None"is it not possible to show my real ip behind a curl request..?

You can use the CURLOPT_HTTPHEADER option. Keep in mind that the name of the header is really X-Forwarded-For. So...

$ch = curl_init('http://dawhois.com/my_ip_address.php');$headers = array('X-Forwarded-For: ' . $_SERVER['REMOTE_ADDR']//Add additional headers here.);curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);$result = curl_exec($ch); curl_close($ch);

did you guys test those codes..?i try em and still "IP Behind Proxy = None"what does it show for you guys..?

Shows the same thing...Perhaps the site uses a different technique to detect proxies, or it only assumes a proxy if the proxy's IP (i.e. your server's IP) is among a certain whitelist of known proxies.
