I want to modify the drupal .htaccess to skip the default rewrite rule for a particular subdirectory and was wondering how I go about that. I searched drupal.org didn't turn up anything, read the Apache rewrite docs and got a headache ;-), and tried a few lines like the following, but no luck:

  RewriteCond %{REQUEST_FILENAME} ^dirname.*

  RewriteRule skip=1

Any pointers would be most welcome - thanks.
