The htaccess code I use for all my/client sites:
# canonical redirect to no www
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
# protect wpconfig at all cost
<files wp-config.php>
Order deny,allow
deny from all
</files>
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
That will 301 redirect to non-www version of the site (personal thing, i don’t like the extra chars). It will help protect your config file and add the typical wordpress mod_rewrite code…
If you need it in that “mysite2009” directory then add that but my code assumes root.
