About Streamed movies behind a firewall
QuickTime uses the Real Time Streaming Protocol (RTSP) to send video and audio over the Internet. Some institutions may have a firewall that prevents movies streamed by RTSP to be viewed by clients behind a firewall. To overcome this, QuickTime can stream video and/or audio using the Hypertext Transport Protocol (HTTP)--the protocol used by the Web. Note: Playback performance may lag when using HTTP streaming instead of RTSP. In addition, the streaming server must also have a streaming over HTTP feature.
