# Shoutcast and Icecast - streaming audio
# Pattern attributes: good slow notsofast
# Protocol groups: streaming_audio

#
# Original pattern contributed by Deepak Seshadri <dseshadri AT
# broadbandmaritime.com> who says "The difference between [Shoutcast and
# Icecast] is not clearly mentioned anywhere. According to this
# document, my pattern would filter JUST shoutcast packets."
#
# Should now match both Shoutcast and Icecast. Tested with Winamp (in
# 2005) and Totem using streams at dir.xiph.org (in Nov 2007).

shoutcast
# The first branch looks for an HTTP request that looks like it is asking for
# a SHOUTcast stream. The second branch looks for the server's reply. However,
# some (newer?) servers answer with "http/1.0 200 OK", not "ICY 200 OK", so
# this will not work.
# This pattern was discovered using Ethereal.
