I assumed one would need to check an HTTP header or something on the response, and I think I guessed it right. I used Wireshark to monitor some traffic to/from a SHOUTcast server and I spotted this in the response: content-type:audio/mpeg That would be MP3, I guess, and that's how you know what kind of stream it is.

Looking at the data with Wireshark. This is a priceless tool if you are doing any sort of network analysis or programming. That and reading the relevant RFCs which are the definitive specs. -- Dee Earley (dee.earley(a)icode.co.uk) i-Catcher Development Team iCode Systems (Replies direct to my email address will be ignored.
