In this example, let's say we want to display something unique based on the id value in the URL. For example, let's say we have these two URLs:

• www.example.com/MVC/Home/Index?username=Jeremy
• www.example.com/MVC/Home/Index?username=Natalie

When Jeremy is requested, we want to display "Welcome Jeremy". When Natalie is requested, we want to display " Welcome Natalie" Add the following to Index string of the HomeController class:

public string Index(string username)
{
    return "Welcome " + username;
}
