How to stop server from shutting down between requests?

Hello, I was wondering if there was a way to make the server stay on between requests. I have a project deployed right now, and if somebody important, say a recruiter, were to click on the link it would take forever to load as the server would have to boot up before it could handle the request.

I am on the shared cpu x 1 256mb platform right now.

The speed of the server itself once it is online is fine, so I would prefer not to spend money, however this is an option if necessary.

Update your fly.toml with auto_stop_machines = false
