Using Protocols
Clients can connect to a Windows Media proxy server using either the MMS, HTTP, or RTSP protocols. (To make a Windows Media server act as a proxy, you must enable a proxy plug-in.) The proxy server can then connect to the requested origin server by using the HTTP, RTSPU, or RTSPT protocols. The proxy server cannot use MMS to connect upstream. Therefore, if a client connects to the proxy server using either MMSU or MMST, the proxy plug-in must instruct the server to roll over to an alternate protocol when connecting upstream. The following table identifies the protocols that can be used by different versions of Windows Media Player.
Protocol |
Client |
|---|---|
HTTP |
Windows Media Player 6.4 and later can use HTTP to connect to the proxy server. |
RTSP |
Windows Media Player 9 Series and later can use RTSP to connect to the proxy server. |
MMS |
Windows Media Player 7.0 and later can use MMS to connect to the proxy server. However, the server must roll over to a different protocol to connect to an origin server. |
Note
The MMS protocol is not supported in Windows Server 2008 operating systems. Versions of Windows Media Player earlier than 9 Series support only the HTTP and MMS protocols (hey do not support RTSP) If you want a running on a Windows Server 2008 operating system to communicate with versions of Windows Media Player earlier than 9 Series, you must configure the server to support HTTP.
