title: Check if page change request is result of browser back/forward button in JQueryMobile
body: <p><strong>What I got working so far:</strong></p>
  
  <p>Store a few pages in the DOM so that when the user uses the browser's back or forward button it will quickly show the page without reloading it.</p>
  
  <p><strong>What I need help with:</strong></p>
  
  <p>When a user clicks a link to a page that is already in the DOM (for back/forward functionality), I want to remove the requested page from the DOM before jqm processes the request so that the requested page is retrieved from the server rather than the DOM.</p>
  
  <p>If this is possible I'm guessing I need to somehow use the <a href="http://api.jquerymobile.com/pagebeforechange/" rel="nofollow">pagebeforechange</a> event.</p>
  
  <p>Basically, I want jqm to use the DOM only for back/forward navigation. Otherwise I want the page to be retrieved from the server.</p>
