You will probably need to write a custom route handler that 
handles some authentication and returns files in response to a 
user.

Since vibe.d routes handled in order you will need to add such 
route before generic '*' route.

Take a look at this example
https://vibed.org/docs#http-routing

You can probably just write a handler like addUser for 
router.get('*', serveMyFiles) and write your own file handling 
logic.


```d
// PSEUDOCODE

// use this handler in router.get('*', serveMyFiles)
void serveMyFiles(HTTPServerRequest req, HTTPServerResponse res)
{
   enforceHTTP("file" in req.form, HTTPStatus.badRequest, "No file 
specified.");
   // don't just use raw input from the user, users can access 
your whole filesystem with some hackery!!
   res.writeBody(readfile("/users/"~req.form["file"]));
}

```
