i’m trying to track my visitors, i’m using with $_SERVER[HTTP_REFERER],
i have some problem, when users come from https refferal the $_SERVER[HTTP_REFERER] disappear In iOS 6.
in this case, how can i know if user come from refferer or direct, is there another way to know if users come directly ?
If the client does not send a referer header there is no way to know from where he comes.
However, you can determine if the user was on your site before by setting a cookie containing a timestamp and checking if that cookie already exists and how old the timestamp in it is.
