Shoutcast no cache html5 player

[Jannes01]

On every SHOUTcast Streams Status (V2) page, there is a html5 webplayer, which has a nocache function.
When you copy the audio link you see something like "/stream?type=http&nocache=376"
I also have a html5 audio player on my site, and this one is caching sometimes, So how is this done?
I think it is with javascript but i can't find out exactly how to do this?
Anyone can help me with this?
