This article applies to:

• SWG 10.x

Symptoms:

• SWG fails to pass Silverlight streams
• Silverlight does not work through SWG
• The SWG Status Page (displayed while downloads are being scanned) might be delivered to the Silverlight Player, but the Player may be unable to handle this page

Testing:

To determine if the status page is the issue, temporarily disable display of the status page:

1. In the SWG GUI, navigate to Administration > Scanning > Scanning Options
2. Deactivate "Enable Status Page"
3. Commit

Test the Silverlight player again. If the stream plays, then the player cannot handle the status page (which is sent to the client in the background).

Resolution:

To disable the status page only for this specific content:

1. In the SWG GUI, navigate to Administration > Scanning > Scanning Options
2. Activate "Enable Status Page" again
3. Select tab "Activate"
4. Under "Unless" add the following (do not delete any existing items):

   Extension Is / xaml
   Extension Is / xap 
   Extension Is / xbap

   Mime Type Contains / xaml+xml
   Mime Type Contains / x-silverlight-app
   Mime Type Contains / x-ms-xbap
