Today, I want to send a POST request from Siemens PLC as a UDP datagram to an apache webserver running PHP and Laravel. It's definitely something wrong with me. It's like 98% failure. :D

why udp?

@stop the idea was that its smaller, less traffic, doesn't need constant connection. But apparently to build up complete http post request at plc and then meaningfully receive it and route it in laravel is f.. painful.

@blindXfish if you want to trigger an http-post, you need an service that receives the request an sends it to your application. The easiest way is an socat as an receiver that proxies the request to the php-fpm. The answer is thrown away.
