MS-HTTP is one of the Microsoft-bastardized standard formats (similar to MS-[[RTSP]]). A standard-compliant [[HTTP]] client is not necessarily capable of downloading MS-HTTP content, since various extra (non-standard) HTTP calls need to be made before the server will start streaming media content.

MS-HTTP servers stream [[ASF]] data. A sample source for MS-HTTP data is [http://wms.absoluteradio.co.uk/absoluteradio.co.uk/vr_lo Absolute Radio]. FFmpeg's current (r24794) [[HTTP]] implementation can not yet play this stream:
