title: Overriding AuthorizeAttribute in MVC 4
body: <p>In my application, I want to redirect the authorized user to update their profile page until they have provided required information. If they update profile, then the <code>IsProfileCompleted</code> is set to 'true' in the database.</p>
  
  <p>So, I knows that this can be done by putting check condition in required action of controller.
  But I want to do this by customizing the <code>AuthorizeAttribute</code>.</p>
  
  <p>I Googled and 'StackOverflowed' for information, but got confused. Please guide me.</p>
