The cometd: component is a transport for working with the jetty implementation of the cometd/bayeux protocol. Using this component in combination with the dojo toolkit library it's possible to push Fuse Mediation Router messages directly into the browser using an AJAX based mechanism.
cometd://host:port/channelName[?options]
The channelName represents a topic that can be subscribed to by the Fuse Mediation Router endpoints.
cometd://localhost:8080/service/mychannel cometds://localhost:8443/service/mychannel
where cometds: represents an SSL configured endpoint.
