Final navigation path implementation

As it appeared to be impossible to implement a navigation path the way I wanted to (using the browser's history back function, see my previous post), I've decided to create a limited but robust alternative using the javascript exit function. It's limitation is that the user can only junp back to the previous page (report), and not to pages higher (more to the left) in the path.
Therefore I've created a piece of javascript code just for the last entry in the navigation path, and created a hyperlink only for this entry ('Marap' is the name of the previous page):

<a href="javascript:exit()">Marap</a>

Of course, the user is always able to use the browser history to go back to prior pages by clicking on the Go Back drop down button in the browser's navigation toolbar!
