About referer

[bogu]

I'm doing a traffic module for a site and I encounter a problem. I want to know how to determine witch hits are direct hits on the site and witch hits come from other sites and witch hits have their referrer blocked!
I’m trying something like this:

<?php
	if (isset($_SERVER['HTTP_REFERER'])) {
		if (empty($_SERVER['HTTP_REFERER'])) {
			echo "Referer is blocked!";			
		} else {
			echo $_SERVER['HTTP_REFERER'];		
		}
	} else {
		echo "Direct hit!";
	}
?>

do you have a question then? or are you just letting us know what your up too lately?

Sorry, you are right there is no question in there ....
My question is how can I determine what is a direct hit on my site and what is a referrer blocked?
And if my approach is correct.
