1.4 Relationship to Other Protocols

  • Article

The Windows Media HTTP Streaming Protocol depends on HTTP 1.0, as specified in [RFC1945]. The pipelined mode of the protocol can only be used if the client, the server, and any intermediate HTTP proxy servers support the pipelining feature of HTTP 1.1, as specified in [RFC2616].

This protocol can be used instead of the Microsoft Media Server (MMS) Protocol as specified in [MS-MMSP]. This protocol can also be used instead of the Real-Time Streaming Protocol Extensions as specified in [MS-RTSP]. However, although these two other protocols allow the multimedia data to be transmitted over either User Datagram Protocol (UDP) or TCP, the Windows Media HTTP Streaming Protocol only allows multimedia data to be transmitted over TCP (because HTTP always uses TCP).

Implementations of the client role of the protocol are able to share cookies with implementations of the client role of the Real-Time Streaming Protocol (RTSP) Windows Media Extensions [MS-RTSP] that are running on the same machine.
