+Internet.nl penalizes the use of [0-RTT](https://blog.cloudflare.com/introducing-0-rtt/) because it opens sites up to replay attacks. Since passing the test, I moved all non-idempotent content to other subdomains. Save for some fancy Nginx redirects, everything on the `seirdy.one` domain is static public content. This property made it safe to enable 0-RTT without being at risk of replay attacks. As of right now, I don't pass the test, but I consider the 0-RTT failure to be a false positive.
