Article ID: 925056

  • Microsoft Windows Media Player 10


Consider the following scenario. Microsoft Windows Media Player 10 is embedded in a Web page. The source URL points to a metafile, such as an ASX metafile redirector or ASP. In this scenario, HTTP referrer data is not sent in the request for the metafile to the Web server.


This problem occurs because this functionality was not included in the initial release of Windows Media Player 10.
