Has this been around for long?
Should I be worried?
In the past (who knows right now) one of the versions got cached less and less often, and eventually went into the supplemental index. This doesn't mean that it's a good thing -- splitting PR and link influence between different urls and so on.
It is quite possible for a server to have many urls all pointing to the same "Home Page" -- it happens a lot. Search engines will try to reduce the number of listings if two pages are identical. So the best practice is to help them and help your site. Make sure only one url gets a 200 OK header for any given content -- and especially the Home Page. Have Home Page links point to the domain root, and 301 any other possible urls to the domain root.
