title: Why do we use redirect in Spring MVC?
body: <p>Why do people have to redirect at all if the url is in their own web application?
  Why in Spring people redirect from Controller's handler method to another handler method in the same controller?
  I have heard that redirect is browser based. It is like sending request to the browser to send a request to another URL.
  While forward makes sense as it is used fro within the (spring mvc) application so that the URL on browser's window remains the same.</p>
  
  <p>But is it heroic to use redirect:/url when you can simply send a view name or use forward if need be.</p>
