Navigating back to page that no longer exists

Aug 2, 2013 at 8:05 AM
If a page no longer exists, and you use the back button to navigate back to it, then you have to click back again to get to a page that does exist, and obviously this could happen again etc. I know there isn't any current way of removing a page from the navigation stack, but any ideas how I could get around this? I want to almost check if the page is there before navigating to it, and if not go somewhere else (home maybe?)
