Save some memory by defining the middleware function once

[EvanHahn]

This would probably save a bit of memory:

var middleware = function nosniff(req, res, next)  {
  res.setHeader('X-Content-Type-Options', 'nosniff');
  next();
};

module.exports = function nosniff() {
  return middleware;
};

This would only make a difference if you were using the middleware many times...probably not worth it. Anyone have any thoughts?

Closing this—not worth it.
