Server-initiated push.

This message informs the relevant process that the server is pushing a resource related to the effective target URI of the original request.

A server-initiated push message always precedes the response to the original request.

This message will not be sent when using the HTTP/1.1 protocol because it lacks the concept of server-initiated push.

StreamRef
