How to Get the Request Source Hostname in Node.js? or Node.js Request Source Hostname: How to Retriev

Honestly, headers are a mess with proxies.

For nodejs request source hostname, I’d recommend using a middleware like `express-request-host`:
```javascript
const requestHost = require('express-request-host');
app.use(requestHost());
```
It normalizes everything and handles edge cases.
