hi friends... I have a HUGE problem about that. I nee to change referrer in this structure. First site will post data so second site and second site cannot check referrer value. first page on FIRSTSITE.COM/test.php Code: <html> <head> <title></title> </head> <body> <form action="http://www.SECONDSITE.com/testreferrer.php" method="post"> value: <input name="field1" type="text" /> <br /> <br /> <input id="submit" type="submit" value="submit" /> </form> </body> </html> second page whick checks the referrer on www.SECONDSITE.com/testreferrer.php Code: <html> <body> <form action=" method="post"> <br> Your value is: <?php echo $_POST["field1"]; ?> <br> referrer: <?php echo $_SERVER['HTTP_REFERER']; ?> <br> </form> </body> </html> normally testreferrer.php shows http//www.FIRSTSITE.COM/test.php as referrer value. I want to change it http://www.somesite.com/test.php I googled and found out some says "its impossible" as browser sends referrer value but some others claims they change it. Though I tried almost every code piece I found I could not make it run. my servers are linux and I think there should be a way to achieve this. any ideas please ?
