Lighttpd and clean URLs

[Wolphie]

Ok, I know about having to set the 404 error handler directive in the lighttpd configuration file or a .htaccess file.

But what's required to achieve actual clean URLs with lighttpd? Are rewrite rules still required? If so, anybody got a simple example? (I suck at regular expressions). And what's needed to achieve this where PHP is concerned? I know apache needs to use mod_rewrite and needs rewrite rules, and then you need to examine the query string and explode it in PHP.
