There is a windose server 2003, it lives a number of basic services.
Also it spinning and two systems for viewing statistics and managing these services.
Actually I want to protect all of these systems and the website from each other.
An additional system, very specific and written in PHP.
But they also are open to and are free, i.e. everyone wants to have access for detailed study.
For nix* systems can run virtual hosts from different users, for Windows I have these modules not found.
What can you advise for maximum differentiation, so that the breaking of one does not hurt the other virtual hosts was not provided any access to other files?
PS maniachenko the solution is to put nginx and dev. Move all dev and nginx to proxy to it. +)
