This option allows a configurable delay after receiving SIGTERM (or
SIGINT) but before the HTTP server stops accepting new connections. It
is quite useful for distributed systems where callers are only notified
asynchronously (e.g. via service discovery) that a service is being shut
down; it prevents the shut down from occurring prior to callers
processing the notification.
This required some minor refactoring to allow the Shutdown() method on
http.Server to be accessed.
Rather than setting "Cache-Control: no-store", use "no-cache". The
difference is that "no-store" tells the browser that it must always
completely re-fetch the resource; whereas "no-cache" means that the
browser can write the resource to disk but must re-validate it (e.g.
using Etags) before re-using it.
