No, unfortunately I have no experience in any of these languages. 'My languages' are ANSI C, VB.Net and C#. I will soon add Python to that list, for my work. But for now that's it. As you probably can see from my question, I am a newbie when it comes to network communication.

Thanks for pointing my to Mosquitto. It will be a possibility to explore, even though I hoped to find a solution without any third party tools. But as I understand from all these answers, this is probably impossible at the moment. Whatever the solution will be, it will take me to new horizons. I hope to come back to this thread and share my experience.

Kind regards
Dan

I'm not a big .Net user but I am sure you could really easily knock together a simple ASP.Net app in either C# or VB.Net that takes a POST command and save the contents. You could run it in IIS on your laptop.

This looks like a good starting point: https://www.codeproject.com/Articles/137979/Simple-HTTP-Server-in-C

Thanks again to all who contributed,
