/**
* Bayeux Reconnect implementation.
* See http://svn.xantus.org/shortbus/trunk/bayeux/protocol.txt for the technical
* details.
*
* Upon connection, clients are implicitly subscribed to a connection-specific
* channel located at:
*
* /meta/clients/[SOME_UNIQUE_CLIENT_ID]
*
* The client ID is used in reconnection. The reconnect verb allows occasionally
* connected clients and the posting of messages for pre-authenticated systems.
*
* // reconnection is very similar to initial connection:
*
* //-----------------
* // CLIENT -> SERVER
* //-----------------

* "connectionType": "iframe", // FIXME: is this necessaray?
* // optional
* "authToken": "SOME_NONCE_PREVIOUSLY_PROVIDED_BY_SERVER"
* }
