title: How to remove HTML5 persistant databases in UIWebView?
body: <p>I have a native application that uses a UIWebView and notice that with sites like Google, they are using an HTML5 local database for storing information.  I am using native APIs for clearing items out of the cookie store, but clearing the persistent cookie store does nothing to remove these local databases.  Is there a way to remove them through a native API?</p>
  
  <p>UPDATE:</p>
  
  <p>Is there a way to do this through a non-native API or javascript?</p>
