This guide explains how you can install Drupal 6.4 on a lighttpd web server on Debian Etch. Drupal comes with an .htaccess file with mod_rewrite rules (for Apache) that do not work on lighttpd. Without this .htaccess file it is not possible to have clean URLs in your Drupal installation. Fortunately there is a way to make lighttpd behave as if it could read the .htaccess file.
