Playing with Apache and Robust on a test local grid, to fully secure a grid and providing a website on the same domain, everything going on HTTPS

example:
https://mydomain.net (website)
https://grid.mydomain.net (grid)

So nothing can be intercepted by "the man in the middle", Robust listens only on the internal network, and is exposed only through Apache, on which powerful filters can be set (it's a real webserver lol)

I only have an issue to make the Wifi module working, but when everything will be clean, I will make a tutorial for all this setup.
