This blog now runs on a server that accepts HTTP/2 connections. It is H2O 1.0.0 with a proxy to Apache/PHP.
Since H2O can only proxy to HTTP/1 using plain (no HTTPS) connections, WordPress needs to be told not to redirect to the canonical url. This can be done by adding the following line to wp-config.php: $_SERVER['HTTPS'] = 1;
Building H2O requires quite some knowlegde of Linux. And I wouldn’t recommend using it in production yet. But it surely is fun to experiment with.
