Welcome to WebmasterWorld, greeny!

I think you are referring to this older thread about "pinging" an external site with javascript [webmasterworld.com]?

In the block that says "DO SOMETHING HERE" is where you might add some code to redirect the visitor like:

location.href = 'http://www.example.com/';
