If you want to disallow the indexing of the Hatchbox domains for your apps you can do either of the following:
- Set up your robots.txt for that domain (your app should respond to that route instead of using a static file)
- Customize your app's Caddy routes to include %{hatchboxapp_robots} which will set up a robots.txt for that domain to deny all. You can find that Caddy config under the app's Edit page.
