how to implement fastcgi_cache on a Debian+nginx+ISPCFG3 isntal?

[Ovidiu]

The server has been set up according to: http://www.howtoforge.com/perfect-se...nx-ispconfig-3

I'm just wondering how to add this tutorial to it: http://www.howtoforge.com/why-you-sh...h-microcaching

The problem I am facing is that as far as I can see I can't just add some of those directives via the ISPCFG control panel since the order seems important so I guess I'D have to change the templates ISPCFG is using for new sites, right?

And if I'm right, can anyone point me towards where those templates are and if I upgrade ISPCFG I guess I need to update the templates again?
