I have a site which uses htaccess in order to use nice URLs. However I want the htaccess file to leave alone a whole folder and it's content completely. The content of my htaccess file is:

```
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1

```

How should I complete the above code to EXCLUDE completely the folder named "admin"

Many thanks in advance!
