Hello List, I'm searching for a possiblity to cache a realaudio, mp3 and/or a windowsmedia audio stream. The intension, is to reduce the traffic in the lan, because many guys hear the same stream (radiostation) in our house. Now it would be nice, if a proxy, or any other chaching instance would load the stream, and store it in a cache. So the guys could connect to the local streamingserver to hear the cached stream. Sorry for the post in the security list, but I think it is be best list for such questions. best regards, Hans

since I did not see an answer... I don't know a lot about those streaming protocols. but if the stream is available as multicast/broadcast, you "just" need to route that, and your applications receive it. then its only transfered once by design, regardless of the number of clients listening. if it is peer to peer, (which would be pretty bad design for a radiostation broadcast), you cannot do anything to reduce the the load in the lan, but you could add some content modifying proxy, to reduce load for your uplink, and multiplex it to your lan clients, or multicast/broadcast it locally if the clients are able to receive mc/bc. hth, Lars Ellenberg

Hi Lars, many thanks for your answer, okay afak are the radiostations no multicast hosts. Maybe i explained my situation wrong. I search for something like this: I have a virtual MP3-Player, which is able to store the stream of the radiostation in a cache. Now my clients on the lan connect to this virtual-player, which itself is able to stream itself the cached stream. For this, no routing, and so on would be necessary, because it should be a application running on any machine not used for production. Any ideas? best regards
