title: Stop reloading of web app launched from iPhone Home Screen
body: <p>I created a web app and added to my iPhone Home Screen.  When I switch to another app and back, iPhone automatically reload my web app.  This breaks my app flow.  </p>
  
  <p>How do I prevent iPhone from reloading the app?</p>
  
  <p>I have apple-mobile-web-app-capable meta tag enabled to hide Safari toolbar and I don't want to turn it off.</p>
