How to figure out if running on http vs https?

[marcofranssen]

In my api page I'm doing the following:

export default function handler(req, res) {
  const host = req.headers.host;
  const proto = req.connection.encrypted ? "https" : "http";

  //construct url for xml sitemaps
}

However when deploying this code on vercel it seems the request is never encrypted. What would be a Vercel compatible way of checking the protocol?

Hey, @marcofranssen. You can check X-Forwarded-Proto header. As Vercel runs your app behind proxy server like Nginx, it's the only way to get request protocol:

const proto = req.headers['x-forwarded-proto'];

I think my current code also isn't working because of the proxy. How do I enable this trust proxy? What do you mean by that?

Was wrong about req.protocol and req.secure. I edited my comment. Sorry for misleading you.
