Darwin Streaming Server Relay Setting

After installing Darwin streaming Server, you can use VLC to play streaming media files through the RTSP protocol. But now I have a need to send a DSS (assumed to be a machine) on the media file to another DSS (assuming B machine) on the client VLC by accessing the B machine to play the media files of a machine, that is, using B machine as a forwarding server. I found a lot of articles on the internet about configuring DSS, all of which are about how to install and configure playlists, not how to configure forwarding (Relay). There is an article called "Fast Streaming media based on DSS implementation" of the paper referred to the forwarding, but it is configured to play a playlist, the actual playback of the files on the B machine, the B-Machine Media folder under the media files are deleted and will not work. The detailed configuration process was eventually found in http://soundscreen.com/streaming/relay.html. the following records my configuration process as follows, so as not to forget later.

 Description: Using three Windows PC, one (named A,ip address 100.0.0.108) as source server, one (named B,ip address 100.0.0.107) do relayServer, one (named C,ip address of 100.0.0.109) as the client.set up a playlist,a machine on a machine to send the files on this machine to B machine, if C machine can passAccessing the B-machine to play the media file of a machine proves that relay is successful.Configuration steps:
