How to redirect saving the original referrer field?

Question

I have the following PHP redirect script:

if ($country=="IL") { header('Location: http://iquality.itayb.net/index-he.html'); } else { header('Location: http://iquality.itayb.net/index-en.html'); } 

This redirects the user to different pages according to the value of $country . The referrer becomes the redirect page itself.

How to save the original referrer field?

Answer 1

You cannot use header('Referer: SOME_REFERER_URL') because the browser will overwrite it anyway.

If you have iquality.itayb.net redirected goals, then there are several ways to do this:

• Save referent in user session.

   // in your first script save real referer to session $_SESSION['REAL_REFERER'] = $_SERVER['HTTP_REFERER']; // in the redirected script extract referer from session $referer = ''; if (isset($_SESSION['REAL_REFERER'])) { $referer = $_SESSION['REAL_REFERER']; unset($_SESSION['REAL_REFERER']); } else { $referer = $_SERVER['HTTP_REFERER']; } 

• Send referent as parameter:

   // in your first script header('Location: http://iquality.itayb.net/index-he.html?referer=' . $_SERVER['HTTP_REFERER']); // in your refered script extract from the parameter $referer = ''; if (isset($_REQUEST['referer'])) { $referer = $_REQUEST['referer']; } else { $referer = $_SERVER['HTTP_REFERER']; } 

If you want to trick any other server, use something like this:

 $host = 'www.yourtargeturl.com'; $service_uri = '/detect_referal.php'; $vars ='additional_option1=yes&additional_option2=un'; $header = "Host: $host\r\n"; $header .= "User-Agent: PHP \r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Referer: {$_SERVER['HTTP_REFERER']} \r\n"; $header .= "Content-Length: ".strlen($vars)."\r\n"; $header .= "Connection: close\r\n\r\n"; $fp = fsockopen("".$host,80, $errno, $errstr); if (!$fp) { echo "$errstr ($errno)<br/>\n"; echo $fp; } else { fputs($fp, "POST $service_uri HTTP/1.1\r\n"); fputs($fp, $header.$vars); fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); }
