Indeed, there's a third question too, which relates to Nginx.
THIS THREAD is connected, but specifically on this linked page; posts #21 #22 #23 and very clearly, the great post #24 made by @qualiteam which relates Nginx to future issues of XC5, hopefully
starting with XC 5.4.*.*. If that's the case, surely there's an Nginx only version of the public beta too?
