Authorization header

I can not find in the documentation how to set headers for the request.

How can I bypass this check in supertest?

router.use (req, res, next) ->
  return next() if req.headers.authorization is 'somekey'
  res.send 401

I am unable to set a custom header I have token middleware that will verify a jwt token in the ‘x-access-token’ header. but doing something like this

request(app)
  .put('/user/' + a_user_id)
  .set('x-access-token', myToken)
  .end(callback);

The ‘x-access-token’ header is never set

Is there any plan to prevent the automatic lowercasing?
