I have xampp installed on my linux box, and I've modified the httpd.conf file as I have for DTI to point to a different directory:

 "Include /home/john/www/http.include"
 
 The include directory looks like this:
 
 "Alias /projects "/home/john/www"
 
 When I implement this, I try entering the URL "http://localhost/projects" and I get a "Permission denied" error...
