Do you use the URL as a navigation aid (aka redirect if URL is incorrect)?

Figure: Watch the URL working as a navigation aid

MVC gives us great URLs, but you need to help users navigate via the URL. If the user changes a URL, and the route parameters no longer match, you should correct them with a redirect.

public ActionResult Edit(string employeename, int id)
{
    var model = _repository.GetEmployee(id);

    // check for a parameter match and redirect if incorrect
    if (string.IsNullOrEmpty(employeename) || employeename != model.EmployeeName)
    {
        return RedirectToAction(
            "Edit", new { employeename = model.EmployeeName, id });
    }

    return View(model);
}
