For example, if a fetch-backed request timed out in 500ms, and the observable was retried 5 times, there could actually be 5 open connections by the time the retries have run their course. So it's recommended that fetch and other uncancelable backends that do not add their own logic to support cancellation or timeout specification, do not try to manually implement timeout behavior.\n\nJSONP could probably be made to be consistently cancelable, and thus could support timeout.\n\nSo the timeout property should be documented as an optimization, only active if the underlying backend supports it.\n\nAs part of implementing this feature, the `MockConnection` should provide a means of fast-forwarding virtual time.\n","author":{"url":"https://github.com/jeffbcross","@type":"Person","name":"jeffbcross"},"datePublished":"2015-07-01T04:40:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/2812/angular/issues/2812"}
