public void PushPromise(
	string path,
	string method,
	NameValueCollection headers
)

Parameters

path
Type: System.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.

method
Type: System.String

Http request method that would be used by the push request.

headers
Type: System.Collections.Specialized.NameValueCollection

Http request header that would be used by the push request.

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 to ignore the push requests completely. The expectation is based on fire-and-forget.
