header("Location . /xxx.php") and $_SERVER['HTTP_REFERER']

alanzhao

Hi,

correct me if I am wrong,

I found that $_SERVER['HTTP_REFERER'] is empty when a page is redirected using header("Location ./xxx.php"), same with using javascript:window.location.href and using HTML meta tag.

So what's the best way to track incoming refereral sites, maybe an id in query string?

What's your opinion?

in my experience most programs that track affiliates and things use some sort of id sent through the query string and they set a cookie based on it.
