As you can see below, the viewer shows a tree structure representation of the AMF0/AMF3 message in Flex so you can easily inspect the Flash Remoting requests and responses. AMF is the Action Message Format. AMF is a proprietary data format created by Macromedia (now Adobe) and used by different mediums: Flash Remoting, ByteArray, IExternalizable, NetConnection, NetStream, LocalConnection, Shared Objects and more.
Please refer to "http://osflash.org/documentation/amf" to find more information about AMF.
