Answer 2

+1 A:

what language?

with javascript you can use : document.referrer with php you can use : $_SERVER['HTTP_REFERER']

however, there is NO method in any language that is 100% accurate, do to the ability to spoof headers.

Answer 3

+3 A:

Yes, using the HTTP header called "Referer" (no, that is not a spelling mistake, that is actually the name of the header).

For instance, in PHP you would do this:

<?php echo "You came from this site: <b>".htmlspecialchars($_SERVER['HTTP_REFERER'])."</b>";

The same code in JavaScript:

document.write("You came from this site: <b>"+document.referrer+"</b>");

This could output:

You came from this site: http://www.mywebsite.com/index.html

Strictly speaking, it *is* a spelling mistake, but it's *their mistake*, not yours =) +1

Is there a way a website can accurately determine the source domain that reached it?
