Hi,
i am running some google campaign and tracking them as well.
In my program while tracking from which referer url it has come, for some referer the $_SERVER['HTTP_REFERER'] value is blank. I mean, For some click it is blank and for some clicks referer value is there.
Can anybody has the idea about when this one is possible.
one possiblity is if you type the URL directly then the referer link will be blank. but when i tried from the google adwords PPC site (preview ads section) then also http_referer is blank.
