How can I avoid duplicate content in ASP.NET MVC d

Question

Edit: Now I need to solve this problem for real, I did a little more investigation and came up with a number of things to reduce duplicate content. I posted detailed code samples on my blog: Reducing Duplicate Content with ASP.NET MVC

First post - go easy if I've marked this up wrong or tagged it badly :P

In Microsoft's new ASP.NET MVC framework it seems there are two things that could cause your content to be served up at multiple URLs (something which Google penalize for and will cause your PageRank to be split across them):

• Case-insensitive URLs
• Default URL

You can set the default controller/action to serve up for requests to the root of your domain. Let's say we choose HomeController/Index. We end up with the following URLs serving up the same content:

• mydomain.com/
• mydomain.com/Home/Index

Now if people start linking to both of these then PageRank would be split. Google would also consider it duplicate content and penalize one of them to avoid duplicates in their results.

On top of this, the URLs are not case sensitive, so we actually get the same content for these URLs too:

• mydomain.com/Home/Index
• mydomain.com/home/index
• mydomain.com/Home/index
• mydomain.com/home/Index
• (the list goes on)

So, the question... How do I avoid these penalties? I would like:

• All requests for the default action to be redirected (301 status) to the same url
• All URLs to be case sensitive

Possible?

i really don't know how you are going to feel after 8 years but Now ASP MVC 5 supports attribute routing for easy to remember routes and to solved duplicate content problems for SEO Friendly sites

just add routes.MapMvcAttributeRoutes(); in your RouteConfig and then define one and only route for each action like

    [Route("~/")]
    public ActionResult Index(int? page)
    {
        var query = from p in db.Posts orderby p.post_date descending select p;
        var pageNumber = page ?? 1;
        ViewData["Posts"] = query.ToPagedList(pageNumber, 7);         
        return View();
    }
    [Route("about")]
    public ActionResult About()
    {
        return View();
    }
    [Route("contact")]
    public ActionResult Contact()
    {
        return View();
    }
    [Route("team")]
    public ActionResult Team()
    {
        return View();
    }
    [Route("services")]
    public ActionResult Services()
    {
        return View();
    }
