+# SignalR WebSocket upgrade. The /hubs/ block below sets the "Connection" header
+# to this variable: "upgrade" when the client sends an Upgrade header (WebSocket),
+# "close" otherwise (long-polling). nginx has no built-in $connection_upgrade, so
+# it MUST be defined here in the http context or nginx fails config test on start
+# ([emerg] unknown "connection_upgrade" variable) and keeps the old config.
