How do I properly set up a proxy in Node-RED for secure and efficient communication?

Hey! Just wanted to add that if you’re using Docker to run Node-RED, you can set the proxy vars in your docker-compose file. Makes it super easy to manage.

Here’s a snippet:
```yaml
environment:
- HTTP_PROXY=http://yourproxy:port
- HTTPS_PROXY=https://yourproxy:port
```
Works like a charm!
