 Some standardised message formats are used for common message types - they
 are detailed below.
 
+Note: All consumers also receive the channel name as the keyword argument
+"channel", so there is no need for separate type information to let
+multi-channel consumers distinguish.
+
 HTTP Request
 ------------
 
 Represents a full-fledged, single HTTP request coming in from a client.
+
 Contains the following keys:
 
-* request: An encoded Django HTTP request
-* response_channel: The channel name to write responses to
+* GET: List of (key, value) tuples of GET variables
+* POST: List of (key, value) tuples of POST variables
+* COOKIES: Same as  ``request.COOKIES``
+* META: Same as  ``request.META``
+* path: Same as  ``request.path``
+* path_info: Same as  ``request.path_info``
+* method: Upper-cased HTTP method
+* response_channel: Channel name to write response to
 
 
 HTTP Response
 -------------
 
 Sends a whole response to a client.
+
 Contains the following keys:
 
-* response: An encoded Django HTTP response
+* content: String of content to send
+* content_type: Mimetype of content
+* status_code: Numerical HTTP status code
+* headers: Dictionary of headers (key is header name, value is value)
+
+
+HTTP Disconnect
+---------------
+
+Send when a client disconnects early, before the response has been sent.
+Only sent by long-polling-capable HTTP interface servers.
+
+Contains the same keys as HTTP Request.
+
+
+WebSocket Connection
+--------------------
+
+Sent when a new WebSocket is connected.
+
+Contains the following keys:
+
+* GET: List of (key, value) tuples of GET variables
+* COOKIES: Same as ``request.COOKIES``
+* META: Same as ``request.META``
+* path: Same as ``request.path``
+* path_info: Same as  ``request.path_info``
+* send_channel: Channel name to send responses on
+
+
+WebSocket Receive
+-----------------
+
+Sent when a datagram is received on the WebSocket.
+
+Contains the same keys as WebSocket Connection, plus:
+
+* content: String content of the datagram
+
+
+WebSocket Close
+---------------
+
+Sent when the WebSocket is closed by either the client or the server.
+
+Contains the same keys as WebSocket Connection, including send_channel,
+though nothing should be sent on it.
