This is our current solution to allow access to .well-known folder using deprecated feature from Static-buildpack. In the future, we need to migrate to nginx-buildpack when it is added to cloudfoundry.

HOW TO:

Move all the files you need for .well-known into "./site/.well-known"

Push the app and map subdomain.example.com/.well-known to this app using the following command:

cf push securitytxt -d example.com --hostname subdomain --route-path ".well-known"  

OPTIONAL:

You can also modify manifest.yml to add the route in there instead of using arguments in cf push command. This is useful for when you want to map this same app to multiple /.well-known routes for multiple subdomains Note that when you add route option into manifest.yml, you can no longer adding route using cf push command arguments.
