I have a custom domain forwarded to my fly.io app and I did the whole fly certs add your.example.com and it works fine.
But is it possible for me to forward my domain to a specific url? say, when someone tries to open test.example.com for them to go into myapp.fly.dev/test/dir2/test.html ?
Thank you
Hi,
Not as far as I know 
. There is a way to add custom headers to the response …
… but it doesn’t document setting a code.
I’d assume you have to do that in your app. It should just be a few extra lines. Every language has a way to match a host and/or path and return a response (like a redirect to somewhere else) e.g Node/Express would probably be
app.get('/', function (req, res) {
res.redirect('https://www.example.com/example');
});
i am doing this for uptime kuma.
where do i add this code? and how can i edit my fly.toml since my app is already deployed?
Hi,
Like I say, I don’t think you can do it in fly.toml
So you would need your app/code to do it.
How is impossible to answer - you’d have to look at your app’s code/framework. E.g for Node you might be using Express … so this kind of thing.
But of course if you are using Laravel, Django … etc, each would have their own way to route/redirect.
