I have this .htaccess file in WordPress. It's located at /public_html/ (web root). I need to exclude a folder (csNewsAd) from the rewrite engine. I've tried this, based from another question similar here at SO, but didn't work at all.
AddHandler x-httpd-php5 .php
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^/csNewsAd($|/) - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
RewriteCond %{REQUEST_URI} !^/(csNewsAd|csNewsAd/.*)$
instead of
RewriteRule ^/csNewsAd($|/) - [L]
