This is a very similar question as How to enable directories starting with "."?.
However unlike the situation in that topic, I would like to do this on a Glitch static site.
I need a file in the .well-known directory to be visible. Can this be done? or would I need to change my site to an app to do this?
this could have changed as their post was 3 years ago. but for the mean-time this should answer your question!
how could that solution work?
idea 1: it only makes it work while the project container is awake. this may be sufficient for some manual verification tasks
idea 2: glitch somehow parses the start command and determines which files to mirror into its static site storage
could someone check how it behaves when the project container is asleep?
