PJAX loads html from your server into the current page without a full page load. It's ajax with real permalinks, page titles, and a working back button that fully degrades.

Use history.pushState() to change the browser URL without reloading the page. http://diveintohtml5.info/history.html

You can then add an event listener to the popstate event and react accordingly when the back button is used.
