Server does not respond to CORS preflight requests

[ghost]

First of all: Thanks for this project!

I had to adapt your code in order to make it work with a browser which does preflight requests to check CORS. I've added the following to make it work:

server.route({
      method: 'OPTIONS',
      path: options.uploadRoute,
      handler: (req, h) => h
        .response()
        .header('Access-Control-Allow-Headers', req.headers['access-control-request-headers']),
      config: {
        cors: {
          origin: [ '*' ],
        },
      }
    });

As I'm not an expert on http file upload, I can't say if that code covers the general case. It worked for me..

Interesting. Can you tell which browser is effected? I'd like to investigate further.

In my case: Chrome 62.0 and Safari 11.0

and I'm making a request from localhost:3000 to localhost:8989 (that's why the preflight request takes place)

The preflight request/response looks like this:

Afterwards it's followed by the actual POST request

Thanks for the additional details. Strange enough the upload server should be fine out of the box with preflight request. I just saw that the syntax that you posted stems from hapi 17.
I hope to upgrade the server to hapi 17 soon, then your snippet should come in handy. Thank you.
