It's kinda sad that you can't just run a web server and host your own homepage anymore. You need to mess with your webserver config to make it spam the client with a dozen HTTP headers to disable FLoC, enable HSTS, set this weird same site origin policy thing, disallow iframe embedding...
Luckily enough someone had the idea to make it so HTTP headers will be compressed too, so we can add some more before the request header completely fills up the initial RWIN of the server.
