Back button to last page

I have a situation where I may want to navigate back to the last page that the use was ... I dont want to use the browser back button or the swf address, but some kind of internal mechanism. Any ideas how this can be done?

You could track the history of the user by tracking deeplinking in the Index. Just store the pastPage var into the index page. And then when the user clicks *backBtn on current page you can then grab that var from the index as to what URL to redirect to. The index page is a great way to pass variables to page that have not be *created yet.

easy.
