Apache2 setting up mod_rewrite and restricting access without .htaccess file - php

Question

I am following this tutorial:
http://www.phpro.org/tutorials/Model-View-Controller-MVC.html
The tutorial states you should use an htaccess file. However, the Apache2 documentation advises you to enter your .htaccess rules into the standard configuration files for better performance.
I'm working in /etc/apache2/sites-available/default.
This is what I have so far:
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order Deny,Allow
Deny from all
</Directory>
<Directory /var/www/>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?rt=$1 [L,QSA]
</Directory>
<Location /index.php>
Order Allow,Deny
Allow from All
</Location>
With these rules, index.php is accessible, but index.php?rt=blog still works, and index/blog or /blog do not. What am I doing wrong?

Answer 1

but index.php?rt=blog still works
You don't have any rules that make it so that doesn't work
and index/blog or /blog do not
You don't have any rules that make URLs that look like that work, though "/blog" should be rewriting to /index.php?rt=/blog.
Try something like:
<Directory /var/www/>
RewriteEngine On
RewriteCond %{THE_REQUEST} \ /+index\.php?rt=([^&\ ]+)
RewriteRule ^ /%1? [L,R]
RewriteRule ^/index/(.*)$ /$1 [L,R]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/(.*)$ /index.php?rt=$1 [L,QSA]
</Directory>
