File Server Locator
This tools provides the static file server URL and ensures that the server is a registered file server.
Why?
Because the file server is used to download custom log files and jar files, we need to ensure that the source is trustworthy.
How?
Each file server is given a JWT token that is hosted on the file server under /verify. This token contains the server address and cannot be used on another server.
Currently, there are only two file servers that can be used.
In the future, there will be ways to add / sign other file servers for personal use.
To change file servers the environment variable CAULDRON_STATIC can be changed to one of the two servers above.
Functions
grabStaticFileServer()
This will return the file server location. If it fails it will return FILE_SERVER_INVALID.
Your app should exit on this error as access to a file server is required.
