public:
 virtual void PushPromise(System::String ^ path);

public virtual void PushPromise (string path);

abstract member PushPromise : string -> unit

Public Overridable Sub PushPromise (path As String)

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 the push requests to be ignored. The expectation is based on fire-and-forget.
