title: How to clear Application cache (HTML5 feature) using JavaScript?
body: <p>Our Web-Application uses Application cache (cache manifest) to restore HTML page and resources in off-line mode. HTML-pages have sessionIDs as params in URI. So, after each logout and login action new HTML-pages are saved to application cache because sessionId was changed in URI. After some weeks working with application some browsers start work slower. And size of Application cache (tested on FF 3.6+) is about 200Mb! After each logout we clear LocalStorage of browser,but how to clear resources from Application storage?</p>
