title: The purpose of "Content-available" in Push Notification Json?
body: <p>The purpose is to send push notification with only badge value &amp; nothing else (no banner).</p>
  
  <p>I integrated parse sdk to test push notification &amp; send this push notification </p>
  
  <pre><code>{
  "alert" :"",
  "badge" :"787",
  "Content-available" : "1",
  "sound" : ""
  }
  </code></pre>
  
  <p>So the push notification got send when app is in background, foreground &amp; when app is killed.
  The purpose to wipe some data on arrival of push notification with badge valve 78 got succeeded.
  I send same notification with "Content-available" : "1" removed but everything worked fine as earlier.</p>
  
  <p>My understanding on "Content-available"  was that putting it's value to 1 will allow push notification with no alert value.</p>
  
  <p>So I am confused or I am missing something to know the meaning of "Content-available" in this push notification JSon.</p>
  
  <p>Thanks</p>
