What's the Content-type: application/x-amf

Action Message Format (AMF) is a binary format used to serialize objects graphs such ActionScript objects and XML, or send messages between an Adobe Flash client and a remote service, usually a Flash Media Server or third party alternatives.

The format is often used in conjunction with Adobe's RTMP to establish connections and control commands for the delivery of streaming media. In this case, the AMF data is encapsulated in a chunk which has a header which defines things as the message length and type (whether it is a "ping", "command" or media data).
