title: Loading xhtml pages in div
body: <p>I am looking for an alternative of iframe to load xhtml pages in a website. Handling back and refresh events in iframe is not so easy. </p>
  
  <p>The best way I found was loading the page in a div when user clicks an item from side menu. But it refreshes entire page(including menu).  In Facebook and Google+, the Menu bar is not refreshing when user clicks any link in div. Instead the contents in divs and url changes. Inspecting their Javascript is not so simple. I would like to get the idea behind this. Expecting suggestions.</p>
