RewriteEngine On Turns on mod_rewrite (providing it's been enabled in the apache configuration) RewriteCond %{REQUEST_FILENAME} !-f If the request is not for an existing file... RewriteCond %{REQUEST_FILENAME} !-d ... or for an existing directory.. RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] ...then redirect everything to 'index.php' in the current folder, assigning the requested url to the 'q' variable. The [L,QSA] part tells mod_rewrite to skip any remaining rules (L for Last) and append a querystring, if any.
I'd recommend you take a look at the .htaccess from a default Drupal install; it's got a few extra rules that help with security (eg preventing access to .module files).
