Tracking across domains is not easy.
If you want to catch a user coming from www.w1.com that goes to www.2w.com,
or vise versa, both domainowners must agree to the tracking.
We you go to w2 from w1, w2 receives the information where you come from,
nothing more or less. (HTTP_REFERER)
If w2 wants to share this information with w1, fine.
If they don't, there is no way for w1 to find out where the visitor went.
What is it excactly you want to achieve?
If you want to pass information from w1 to w2, you can also use the url
itself by appending some info, eg:
[from w1]
<a href="http://www.w2.com?id=38726487234">go to w2</a>
[from w2]
if (isset($_GET["id"]){
// do something with $_GET["id"]
}
This can also be done with a form and method POST.
