Here's how the field works. You go to the website of Company X (www.x.com) and
there's a link to the webpage of Company Y (www.y.com). You click the link and
go to y.com. Here, Company Y can see that you came from x.com.
On the other hand, if you were at x.com and decided to visit y.com by typing it
in to the address bar, Company Y would not know you were currently at x.com.
Also, if you set up a redirect/default homepage on the server then this is just
sending that page to the browser instead. This is not the same as being
reffered them from a link. Hence, the field will be empty.
Hmm, HTTP_REFERER. One huge source of confusion.

Consider using Server_Name instead.
