public static interface ServerSession.Extension
Extension API for ServerSession.
Implementations of this interface allow to modify incoming and outgoing messages
for a particular session, before any other processing performed by the implementation
but after BayeuxServer.Extension processing.
Multiple extensions can be registered; the extension receive methods are invoked in registration order, while the extension send methods are invoked in registration reverse order.
