Without diving into the code but rather asking first if anybody has my answer before I have to dig... Can anybody tell me why the feature requires Apache etc.? As I said I haven't studied it yet, and only suspect it could require .htaccess URL rewriting. If that is all it is, I can easily strip the concept out of an Apache .htaccess file and implement the same thing in my Nginx server blocks. Or is it something else? I think it's smart to simply ask the community and see if somebody already knows the answer, rather than my doing a bunch of code diving. If I knew the reason behind the Apache etc. restriction it would make it easier in my code diving. Thanks!
