Case Sensitive Routing in MVC4

Question

Does anyone know if it is possible to have Case Sensitive routing in MVC.

I would like as follows to point to different articles.

example

http://my.ie/uRl --> doc 1

http://my.ie/Url --> doc 2

Would love to hear if this can be done.

Answer 1

You could use Router Constraints and regular expressions like that:

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        new { id = @"\d+", action=@"[A-Z]+"  }  //Parameter constraints
        );

So, just think about constraints you want to apply in terms of regular expressions

Answer 2

Given MVC is an IIS platform (and windows itself is insensitive) I don't know if you're going to have much luck. However, if you're using it to serve up files you can create a fallback route that then takes it a step farther (and parses it appropriately). eg

routes.MapRoute(
  "File_Fetch",
  "{filename}",
  new { controller = "File", action = "Fetch", filename = UrlParameter.Optional },
  new { filename = @"^.+$" }
);

public class FileController : Controller
{
    public ActionResult Fetch(String filename)
    {
        // /Url -> filename = "Url"
        // /uRl -> filename = "uRl"
        return File(...);
    }
}

So now instead of trying to use the routing to differenciate cASe you can interrogate the incoming parameter and serve it up as you see fit.
