    // Using Wikipedia as an example. I'd rather use Netty's own website
    // but the server (Cloudflare) doesn't support OCSP stapling. A few
    // other examples could be Microsoft or Squarespace. Use OpenSSL's
    // CLI client to assess if a server supports OCSP stapling. E.g.:
    //
    // openssl s_client -tlsextdebug -status -connect www.squarespace.com:443
    //
    String host = "www.wikipedia.org";
