Use auth in server header.

[cadesalaberry]

Check the docs http://mcavage.me/node-restify/

Should look like this:

var restify = require('restify');

function customAuth(req, res, next) {
  if (req.header('X-Custom-Auth') == "the right one") {
    next();
  } else {
    res.json(401, {code:401, message: "Auth failed."});
    next();
  }

  restify.use(customAuth);
}
