The HTTP request sent by my workstation to the webserver when I click
to play "So, The Circus Is Back In Town" by Cato Salsa Experience
shows a request for a .swf file, and a sending of a matching MIME type.
This a tcpdump processed with tcpshow of the HTTP request and reply
for the song file itself:
