Proxy: support for connection upgrade (101 Switching Protocols). This allows to proxy WebSockets by using configuration like this: location /chat/ { proxy_pass http://backend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } Connection upgrade is allowed as long as it was requested by a client via the Upgrade request header.
