title: How can I send a message parameter to spring login page using a query param?
body: <p>I want to send a message to be displayed on login page. I was thinking to use a query param, something like <code>myapp/login?m=4</code> and then handle this param in controller, but it seems that I am redirected back to myapp/login.</p>
  
  <p>Any idea which is the best practice to achieve this?</p>
