Cookie not set with SameSite attribute

lib/create-app.js の 305 行目付近から始め、express-session のドキュメントと照らし合わせて express-session の Cookie 設定を確認します。SameSite Cookie の適用時に Android Chrome で nssidp.sid の動作を再現し、その後、認証済みの Solid アプリが、サポートされている接続モードを壊すことなくセッションを確立して使用できることを確認します。

As noted on solid-auth-client https://github.com/solid/solid-auth-client/issues/151, Chrome is requiring third party cookies to be set with SameSite=None and Secure. While this setting is not yet active on desktop, it is active on Android and therefore breaks all Solid apps using the nssidp.sid cookie from .solid.community.
This can still be bypassed by disabling chrome://flags/#same-site-by-default-cookies.
Presumably non-cookie based authentication doesn't have this issue but I'm not sure it's possible to turn off cookie-based authentication at the moment (https://github.com/solid/node-solid-server/issues/672)

I'm not an expert, but it appears the change required is in the definition of the express-session settings
https://github.com/solid/node-solid-server/blob/master/lib/create-app.js#L305
https://www.npmjs.com/package/express-session#cookiesamesite

It may be sufficient to simply use:

    cookie: {
      maxAge: 24 * 60 * 60 * 1000,
      sameSite:'None'
    }

It seems that http connections should also be completely dropped for authenticated sessions because the third party cookie won't be sent without cookie.secure=true anyway.
