title: How to use DIV or IFRAME to display a page within a page
body: <p>I'd like to display a welcome page upon sign in to my company website.  Currently this page has some account summary data/details.  I'd like to be able to use this same space to display billing info but I don't want the user to leave the page they're on.  </p>
  
  <p>How can I accomplish this?  It is imperative that I am able to put the code for this within the page that is already loaded.</p>
