title: phonegap: open external page and then go back to app
body: <p>ok, browsing the questions I've found the right way to load an external page into the phonegap view (i.e. without loosing the session or opening the device browser) as explained here: <a href="https://stackoverflow.com/questions/8596772/how-can-i-load-a-webpage-inside-the-phonegap-webview">How can I load a webpage inside the phonegap webview?</a> 
  and here: <a href="https://stackoverflow.com/questions/5911255/phonegap-for-iphone-problem-loading-external-url">PhoneGap for iPhone: problem loading external URL</a></p>
  
  <p>Next step is: after i've opened an extarnal page (it's owned by me and I can modify it) how can i go back to my local application? Let's say I have a link in the external page and I want the user to be redirected back to a local html page (mypage.html) inside the phonegap application on click. </p>
  
  <p>What url should the link's href attribute have? I've tried setting it to "file:///android_asset/www/mypage.html" but didn't work </p>
