Vibe.d serve files from filesystem

[eXodiquas via Digitalmars-d-learn]

Hello everyone,

I build a web tool that allows people to upload some files. Those 
files should not be public, so I copy them into a folder hidden 
away on the filesystem. But, I want an authenticated user to be 
able to look at them. Those files are PDFs and mp3/4s. So my idea 
was to use an `iframe` with a `src="path/to/file"` but this is 
not working, because vibed wants to map it to a route but there 
is and there should be none. Is there a way to use iframes in 
this way, or do I need to approach this problem differently?

Thanks in advance.
