title: How to get Azure ACS refresh token
body: <p>We are developing a SOA application which uses Azure &amp; ACS as server side components and iPhone &amp; Windows Phone as clients. We were able to establish the authentication scenarios successfully as per the sample available in code plex.</p>
  
  <p><a href="http://acs.codeplex.com/wikipage?title=ACS%20Windows%20Phone%20Sample" rel="nofollow">http://acs.codeplex.com/wikipage?title=ACS%20Windows%20Phone%20Sample</a></p>
  
  <p>ie using passive authentication with Windows Phone Push notification.</p>
  
  <p>Now we are experiencing the authentication token time out which we would like to resolve by adopting the refresh token method. But we didn't find any method to obtain the refresh token while we authenticate first time. ie its not available in the ScriptNotify event of Windows Phone's browser.</p>
  
  <p>Can somebody help to resolve the scenario using refresh_token? Or are there any other method which is better than refresh_token ?</p>
