Shoutcast audio stream without port

[ram130]

Hey guys,

I've seen a few radios stations that somehow don't use a port for their Shoutcast server. I'm wondering, how do you do that? I've seen a few Icecast servers as well. I'd usually see something like live.radiostation.com/stream or something similar. Usually going there you get the audio stream playing.

I understand when they do this it helps those users behind cooperate firewalls.
