Replace protocol with an appropriate protocol type—either mms if the content is on a Windows Media server or http if the content is on a Web server.
Replace servername with the DNS name or IP address of the server that contains the content.
Replace filename with the name of the content that you want to stream to users prior to the multicast content.
The multicast content requested by the user will continue streaming while the on-demand wrapper content plays. Consider keeping the length of the wrapper content short so that the user misses as little of the requested content as possible.
Users that connect to your multicast will receive the content specified in step 5 before being connected to the multicast content.
