            Bug ID: 28823
           Summary: Course of action even after Event Source retry
                    failure.
           Product: WebAppsWG
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server-Sent Events (editor: Ian Hickson)
          Assignee: ian@hixie.ch

As per the spec
https://html.spec.whatwg.org/multipage/comms.html#processing-model-10 , when
EventSource fail to establish the connection first time,
it should retry to connect to given URL after time specified in the "retry"
field/UA default value. But Spec doesn't tell specifically what should be
done if retry attempt fails.

And since this "retry" field is in seconds, Browser should try only once or is
it retry interval(i.e browser should keep on retrying after every retry
seconds).

For eg:
var evtSource = new EventSource("http://www.test.not")
evtSource.onerror = function() {
   console.log(evtSource.readyState);
}

In above case Browsers behavior is :

Firefox retries only once and if it fails to establish the connection to given
URL it closes the connection.

But Blinks keep on retrying for given URL with readyState set to CONNECTING.

Can spec be more specific on this i.e what should be done if it fails to
connect even after retry?
