title: Tiles Framework : refresh only body content
body: <p>we have a Tiles layout page having Header, Menu, Body and Footer. In this layout whenever user does some action in the Menu lists, the whole Layout (Incl Header, menu and footer) is refreshing. I want header,menu, footer to be static, and only body part should get updated.</p>
  
  <p>Is there any way to prevent the refresh of the Header, menu and Footer and update only Body content on the menu click which can be implemented using Tiles?</p>
