Lighttpd

Hi

I have a virtualhost in apache with a <Directory> I would like to rewrite to lighttpd. I'm not using simple vhost.
Is it possible to rewrite the apache <Directory></Directory> block like:

<Directory "/path/to/my/directory/">
RewriteEngine on
RewriteBase /
RewriteRule \.(php|html|htm|xml)$ index.php
</Directory>

to lighttpd syntax?

I'm running latest lighttpd from svn.
Thanks
