title: 404 error on push notification using sample code
body: <p>I got my url from the app. It begins with:</p>
  
  <pre><code>http://sn1.notify.live.net/throttledthirdparty/01.00/
  </code></pre>
  
  <p>and if I navigate to that URL using a browser, I get the message:</p>
  
  <pre><code>Microsoft Push Notification Server
  </code></pre>
  
  <p>I then grabbed the code provided by Microsoft.</p>
  
  <pre><code>http://msdn.microsoft.com/en-us/library/ff402545%28v=VS.92%29.aspx
  </code></pre>
  
  <p>If I take the C# code, and use it as is (changing only the URL, the Payload to be an empty byte array, and changing the "" string to Guid.NewGuid().ToString()</p>
  
  <p>I get a 404 every time.</p>
  
  <p>Because I don't get a 404 from by browser, the content must matter, and the push notification servers are dependent on content, so if I change it to a simple raw notification by removing the notification message and adding (as they recommend):</p>
  
  <pre><code>        byte[] notificationMessage = new byte[] {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08};
          sendNotificationRequest.Headers.Add("X-NotificationClass", "13"); 
  </code></pre>
  
  <p>I still get a 404 every time. I've tried doing toast notifications with the same result.</p>
  
  <p>What am I doing wrong?</p>
