• the default .htaccess_root has to be tweaked to allow vhost config, since the following rules forbid access to the site:

<FilesMatch "(index\.php|\.(gif|jpe?g|png|css|js|html)|var(.)storage.pdf(.)\.pdf)$">
order allow,deny
allow from all
</FilesMatch>

• the rewrite rules based on file location and not only suffix are safer

• misc stuff that could be added to rewrite rules for a vhost setup: favicon.ico, p3p.xml, robots.txt. All of these could be part of the default .htaccess_root but left commented.

• other things that could be left in but commented: usage of mod_gizp for css and js files, expires headers on all design elements
