notice how every 7th click to the link leads to pron, whilst the other 6 leads to MSNBC.com ;-) lol
Also, if you want to see how the incoming works
setup a link somewhere on the net and make the link
a href = "http://www.orbityl.com/ftt/index.php"
then click on the link from your page.
then you can go to
www.orbityl.com/ftt/referer.php
to see what that looks like, and you can change the outgoings, etc.
mess with it all you want.
