transferHeaders accepts an arbitrary number of header names and transfers those respective headers from the request object to the response object. In case of a missing header, middledash calls next with HTTP code 400.

app.use(transferHeaders('foo1', 'foo2', 'foo3')); // arbitrary number of headers
