about rtmp channel

LCDS provides a RTMP channel which is a duplex socket connection between the SWF file and the server. It means the server is immediately notified when the underlying SWF file is disconnected.

In a RTMP channel, the FlexSession on the LCDS server is scoped to the underlying RTMP connection from the single SWF file. while in an HTTP-based channel, such as AMFChannel or HTTPChannel, the FlexSession on the LCDS server is scoped to the browser and wraps an HTTP session. If the HTTP-based channel connects to a servlet-based endpoint, the underlying HTTP session is a J2EE HttpSession object. If the channel connects to an NIO-based endpoint, the underlying HTTP session supports the FlexSession API, but it is disjointed from the application server HttpSession object.
