[StephanKrauss]

Hello,

in my projet there are same directory.

public/index.php
public/javascript/
public/css/

src/action/
src/model/
src/service/

How can i set the document root of the apache ? I will start always with /public/index.php

Can i use a .htaccess file for my css files under /public/css

Your sincerly
