EventSource enables servers to push data to Web pages over HTTP or using dedicated server-push protocols. Event streams requests can be redirected using HTTP 301 and 307 redirects as with normal HTTP requests. Clients will reconnect if the connection is closed; a client can be told to stop reconnecting using the HTTP 204 No Content response code. W3C 2012

The withCredentials attribute must return the value to which it was last initialized. When the object is created without withCredentials presents in the settings, it must be initialized to false. If it has the value true, then set CORS mode to Use Credentials and initialize the new EventSource object's withCredentials attribute. W3C 2012

Inherited methods
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).

This implementation accepts a settings object of type EventListenerOptions.
