CometFilter | A Comet filter, similar to regular filters, performs filtering tasks on either the request to a resource (a Comet servlet), or on the response from a resource, or both.
CometFilterChain | A CometFilterChain is an object provided by the servlet container to the developer giving a view into the invocation chain of a filtered event for a resource.
CometProcessor | This interface should be implemented by servlets which would like to handle asynchronous IO, receiving events when data is available for reading, and being able to output data without the need for being invoked by the container.
