When streaming media using Windows Media Player the content shows as cached, however the content results with 0% bandwidth savings when replayed.
This is caused by Windows Media Player not honouring the ProxySG cache settings by including in the initial request a Cache-Control header with the variable set to No-Cache':
Hypertext Transfer Protocol GET /video.wmv HTTP/1.1\r\n [Expert Info (Chat/Sequence): GET /video.wmv HTTP/1.1\r\n] [GET /video.wmv HTTP/1.1\r\n] [Severity level: Chat] [Group: Sequence] Request Method: GET Request URI: /video.wmv Request Version: HTTP/1.1 >> Cache-Control: no-cache\r\n Connection: Keep-Alive\r\n Pragma: getIfoFileURI.dlna.org\r\n Accept: */*\r\n User-Agent: NSPlayer/12.00.7601.17514 WMFSDK/12.00.7601.17514\r\n GetContentFeatures.DLNA.ORG: 1\r\n
To mitigate this you would need to enable cacheing for your version of Windows Media Player, please visit

As a workaround, you could download the file directly to your computer using a browser and play the file once fully received. Doing this will note result in the
no-cache header and server the content appropriately.
