On site site1.com and many others people use ip showing gif <img src=http://site2.com/yourip.gif> I want to redirect from site2.com to site3.com Header(“Location: http://site3.com/newip.phpâ€); But how to change or blank $REFERER, so site3.com sees as referrer site2.com or blank? Any Ideas? Is there any trick to that?
Sending referrer details or otherwise is up to the browser, not a script. Unless you do a custom request via sockets/cURL - which is unlikely to be what you want.
