Cometd Component
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 Camel messages directly into the browser using an AJAX based mechanism.
URI format
The channelName represents a topic that can be subscribed to by the Camel endpoints.
Examples
where cometds: represents an SSL configured endpoint.
See this blog entry by David Greco who contributed this component to Apache Camel, for a full sample.
