Re: GOAWAY and proxies (#458)

DRAINING is a signal that indicates that the server will be sending a
GOAWAY in the near future, and thus that the client should create a new
connection, but, unlike GOAWAY it does not require the client to stop
sending requests.
This allows for a far more seamless switch-over without requiring the
state-tracking of ALT-SVC.
