Redirecting the back button if the "back URL" is xyz.com

Redirecting the back button if the "back URL" is xyz.com

I am trying to capture the back button and redirect if it is a certain URL, if not just go back like a normal back button.

I've never really messed with the history except for something like this: <a href="#" onClick="history.go(-1)">

Anyone have an example using this plugin: http://www.asual.com/jquery/address/ , or any other plugin that might achieve this?

any direction will help

thanks
