         var msg:CommandMessage = CommandMessage(event.message);

The server message type for authentication commands.

This operation is used to test connectivity over the current channel to the remote endpoint.

This operation is used by a remote destination to sync missed or cached messages back to a client as a result of a client issued poll command.

This operation is used to request a list of failover endpoint URIs for the remote destination based on cluster membership.

Header to specify which character set encoding was used while encoding login credentials.

This operation is used to indicate that a channel has disconnected.

Header that indicates the message is a heartbeat.

This operation is used to send credentials to the endpoint so that the user can be logged in over the current channel. The credentials need to be Base64 encoded and stored in the body of the message.

If a client has a long-poll parked on the server and issues another poll, the response to this subsequent poll should be tagged with this header in which case the response is treated as a no-op and the next poll will not be scheduled. Without this, a subsequent poll will put the channel and endpoint into a busy polling cycle.

Header to drive an idle wait time before the next client poll request.
