Back button of my navigator

[Elvira Nieto Carretero]

I use session variable to save the links navigation that the user press during his permanence in my web site.   But, if the user press the back button of the navigator, my session don't update and the next link that he press appear the step that it had to undo when back button of the navigator was pressed.   do you understand me?... i hope yes.   best desires
