http2 sessions should be closed?

[tmm1]

From the nodejs docs for http2server.close():

Stops the server from establishing new sessions. This does not prevent new request streams from being created due to the persistent nature of HTTP/2 sessions. To gracefully shut down the server, call http2session.close() on all active sessions.

I see where server.close() happens:

http-graceful-shutdown/lib/index.js

Lines 206 to 209 in dd23f5a

	debug('Close http server');
	return new Promise((resolve, reject) => {
	server.close((err) => {

But it wasn't clear to me that the active and idle sessions are being closed correctly?

Is this expected to be covered by the Connection: close header for the http2 case as well?

http-graceful-shutdown/lib/index.js

Lines 120 to 121 in dd23f5a

	if (!serverResponse.headersSent) {
	serverResponse.setHeader('connection', 'close');
