@nuintari earn the money yourself and not the maker of some shady "free" app!
I'd love to know the C2 servers of honeygain for some research.

@elithebearded tested with curl over a squid proxy: curl sets up a TCP tunnel for https, so the server sees a HTTP/2 connection.
But there may be other paths.

With more than a few apache2 logfiles to check in my configuration it took a bit, but there is a clear error message in the default ErrorLog:
AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive.

The fun part (and a reason to investigate http/2): seeing visits with a "I'm a modern browser!" useragent not using http/2.

Enabling http/2 on haproxy at home. On the frontends it works fine (including fallback to http/1.1).
From haproxy to the apache2 backends I see the connection downgrade to http/1.1 for some reason, maybe related to using mpm_prefork for most backends.

All tested using #curl which is great for debugging http(s)

Zorgelijke escalatie: voor het eerst hebben Russische hackers Europese systemen voor duurzame opwekking van energie aangevallen. De hack geldt ook als waarschuwing voor Nederland: zon-en windparken zijn door beperkte veiligheidseisen uiterst kwetsbaar

@briankrebs "Inbound international travel to the United States plays a vital role in the Nation’s economy and promotes cultural exchange and understanding"
sounds like they want to halt the 'cultural exchange and understanding' part and allow the damage to the economy

@alzimon nederlandsespoorwegen.nl was toen te lang en dus ook niet goedgekeurd. En verder leken de regels vooral 'waar Piet zin in had'.
