Javascript tracker and Referrer Tracking?

Hi,

for the past few weeks, it seems that I get more than usual NoReferrers hits within my referers stats.

On the website, I also use my own tracker script :

Here is how I call it :

if (document.referrer)
{
document.write('<'+'img src="http://www.mydomain.com/tracker.php?r=' + escape(document.referrer) + '" style="float:left;" width=1 height=1>');
}


tracker.php only tracks down the referer and creates a cookie.

Could this script interfere somehow with the referers tracking ?

Did anybody have this problem ?

Cheers

 

How come you are using Javascript? Why not use PHP, $_SERVER['HTTP_REFERER']. It would probably require a little bit of change in your script, but you could get the referer in the header of your site store it in a variable and use it in your tracking script which you would have to include.

 

because we use this tracker code on many of our client's website too, and not all are using php behind.

 

Ahhh gotcha. That makes sense.

 

Norton blocks referrer headers by default. I reckon this accounts for quite a few 'no referrer' visitors.
