title: Mobile Safari won't stop caching
body: <p>I'm writing an offline app for mobile Safari.</p>
  
  <p>I have just gotten to the point where it will create the app icon on the home screen and function offline.</p>
  
  <p>Now I want to update the HTML in my app, but it refuses to refresh.
  I've trIed the refresh button, the "clear cache" settings option, I have even taken down the server but safari still shows the page.</p>
  
  <p>Help!</p>
