Parameters

path

String

The URL of the push request. It should be the virtual path of the relative resource that the server wants to push to the client.

Remarks

PushPromise is non-deterministic, and applications shouldn't have logic that depends on it. Its only purpose is performance advantage in some cases. There are many conditions (protocol and implementation) that may cause push requests to be ignored. The expectation is based on fire-and-forget.
