I have an entire website with the following directory structure:

/example.com
    /html (public)
        /css
        /js
        index.php
    /lib
        session.php
        other_lib_files.php
    /views
        index.php
    /models
    /controllers

As illustrated, the html is public, and anything above it is private.

My site now needs to upgrade servers, and the new server (Linux w/ Plesk) has the following structure (reduced to the problematic parts below):

/myplesksite.com
    /httpdocs
        /css
        /js
        index.php
    /private
        /lib
        /models
        /views

What I would THINK is that I should be able to put my /lib, /views, /models, etc in the directory directly above /httpdocs, the same way I had it in my previous server.

Is that possible? Or do I have to put it in private?

I would really love not to have to adjust my internal paths throughout the site if not necessary...
