The StreamingHTTPChannel class provides support for messaging and offers a different push model than the base HTTPChannel. Rather than polling for data from the server, the streaming channel opens an internal HTTP connection to the server that is held open to allow the server to stream data down to the client with no poll overhead.

Messages sent by this channel to the server are sent using a URLLoader which uses an HTTP connection internally for the duration of the operation. Once the message is sent and an acknowledgement or fault is returned the HTTP connection used by URLLoader is released by the channel. These client-to-server messages are not sent over the streaming HTTP connection that the channel holds open to receive server pushed data.

Although this class extends the base HTTPChannel to inherit the regular HTTP handling, it does not support polling.
