You have to manipulate the window.history object
https://developer.mozilla.org/en/DOM/window.historyYou can not manipulate directly
"There is no way to clear the session history or to disable the back/forward navigation from unprivileged code. The closest available solution is the location.replace() method, which replaces the current item of the session history with the provided URL."
All of my cloaking used to be done with JS. And all of my tracking was also done with JS

I used to use that method to kill the current page.
It all depends on what lengths Amazon is going to go to detect this.
Theoretically they could load a JS into their site. They could then yank out the history object and pass it to their server.
I did manage to catch a google manual check that way
