How do I call the method reload, as shown in the diagram, and can I call it in the function node? Which method is used?

Hi @lei1

you would use an HTTP Request node and pass in `msg.headers` set to:

```auto
{
    "Content-type": "application/json",
    "Node-RED-Deployment-Type": "reload"
}

```

The http-response node is only for use with the http-in node, not the http-request node.
