Dass man in .NET C# auch multithreaded HTTP Webserver schreiben kann, dürfte jedem klar sein.
Hier mal ein Klassenbeispiel, das automatisch einen freien Port ermittelt und den NAN_Webserver als Instant Webserver startet.
Wahlweise können PHP, Perl, etc als CGI-ausführende Programme deaklariert werden samt Dateitypen, sowie das Home-Verzeiichnis, und zwar alles direkt aus dem GUI-Designer heraus.
