The HTTP Download Plug-in
When you specify the httpd:// prefix to connect to a Web server and request a playlist, the Windows Media server uses the WMS HTTP Download Data Source plug-in to download the playlist.
- Note If you are downloading a playlist from a Web server that sends an authentication challenge, you must specify a user name and password by using the IWMSPublishingPoint.SetDistributionUserNamePassword (Visual Basic .NET).
After the playlist has been downloaded, the server parses it by using a playlist parser plug-in. If the playlist uses SMIL 2.0, the server uses the playlist parser plug-in for which the Input Format property equals IID_IWMSPlaylistSmilFormat (C34294EA-E111-4FB2-BE6B-EC686A1A9757). Normally, the server uses the WMS SMIL Playlist Parser plug-in. However, if the playlist does not use the SMIL format, you must create a plug-in to parse it, and the server searches through the custom plug-ins until it finds one that can create a playlist object from the downloaded playlist. For more information, see Creating Playlist Parser Plug-ins.
- Note For more information about the SMIL 2.0 Specification, W3C Recommendation, see the W3C Web site.
