This might be how it should work, but let me confirm.

c.req.url is always http, even on https requests:

app.get('/foo', c => {
  // Always http, in prod too
  console.log(c.req.url)
  console.log(c.req.raw.url)
  return c.text('OK')
})

I'm on fly.io, basically a proxy that handles my ssl (plus other things). But in Hono I always get the url as http, and my JWT verification fails. It's easy to fix but I somehow expected the proto to be the same as the original request.

Here's my serve:

serve({
  fetch: app.fetch,
  port: Number(PORT),
})

More details on my use-case

This is specifically a request from QStash. It's a queue thing, works something like this:

curl -XPOST \
    -H 'Authorization: Bearer <QSTASH_TOKEN>' \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com/foo'

Notice the url after the QStash endpoint, that's the callback URL that Hono is listening to, and which I've set it to https. Here's the headers QStash sends:

{
  'accept-encoding': 'gzip',
  authorization: 'Basic xxx',
  'content-length': '203',
  'content-type': 'application/json',
  host: 'example.com/foo',
  'upstash-caller-ip': 'xxx.xx.xx.xx',
  'upstash-message-id': 'msg_xxx',
  'upstash-retried': '0',
  'upstash-signature': 'xxx',
  'user-agent': 'Upstash-QStash',
  'x-forwarded-for': 'x.xxx.xxx.xxx',
  'x-forwarded-host': 'example.com/foo',
  'x-forwarded-proto': 'https'
}

I'm guessing it would be https if I used the https server like shown in the docs:

import { createServer } from 'node:https'
serve({
  fetch: app.fetch,
  createServer: createServer,
  serverOptions: { /* keys */},
})

But I don't need to because of fly.

Correct me if I'm mistaken but it feels like Hono should use x-forwarded-proto to set the correct proto?
