// Note: RtspChannel doesn't transport streams as normal channel does.

// (See RtspChannelChild.h for detail).
|

// The reason for the existence of RtspChannelParent is to support HTTP->RTSP
|
|
// redirection.
|
|
// When redirection happens, two instances of RtspChannelParent will be created:
|
|
// - One will be created when HTTP creates the new channel for redirects, and
|
|
// will be registered as an nsIChannel.
|
|
// - The other will be created via IPDL by RtspChannelChild, and will be
|
|
// registered as an nsIParentChannel.
