title: How to get the domain of a request in ASP.MVC if the server uses a load balacer
body: <p>I have 2 servers: server1 and server2. They are hosted behind a load balncer. That means that when I go to <a href="http://myApp.com" rel="nofollow">http://myApp.com</a> I will sometimes land on server1 and sometimes on server2.</p>
  
  <p>What is the right way to identify the domain that the user entered in a MVC controller (I want to get "myApp.com" and not "server1").</p>
