Process: Main
IncomingMessage
implements the Readable Stream
interface and is therefore an EventEmitter.
Instance Events

Buffer - A chunk of response body's data.
The data
event is the usual method of transferring response data into
applicative code.
Event: 'end'
Indicates that response body has ended.
Event: 'aborted'
Emitted when a request has been canceled during an ongoing HTTP transaction.
Event: 'error'
Returns:
error
Error - Typically holds an error string identifying failure root cause.
Emitted when an error was encountered while streaming response data events. For
instance, if the server closes the underlying while the response is still
streaming, an error
event will be emitted on the response object and a close
event will subsequently follow on the request object.
