Dreamweaver HTML Help needed;

I need some help. When someone clicks on a link in my site it takes them there, (aren’t I good!) but when they hit the back button, instead of them getting a cached copy the site reloads again. There HAS to be an HTML or Javascript code that will prevent this from happening, and someone here must know it and be dying to share it with me right? I have started making my links to open in separate windows, not my preference, so if you need to find a link use the ones in the drop down menus, as they cannot be made to open in separate windows. Test it and see yourself what I am describing. \r
