演进复制HTTP/2 allows a server to pre-emptively send (or"push") responses (along with corresponding "promised" requests) to a client in association with a previous client-initiated request. This can be useful when the server knows the client will need to have those responses available inorderto fully process the response to the original request. 1.2.3.4.5.6.
