I'm running a Kohana setup on my local apache server. I've created a 'htdocs' folder which houses the index.php file in the kohana directory. So that the system files are not available to visitors. Now I wan't to remove index.php from the URL everytime I visit another controller, so I've tried fooling around with the .htaccess provided but can't get it to work. Anybody here with some skill with this? 

The .htaccess file:

```
# Turn on URL rewriting
RewriteEngine On

# Installation directory
RewriteBase /

# Protect hidden files from being viewed
<Files .*>
    Order Deny,Allow
    Deny From All
</Files>

# Protect application and system files from being viewed
RewriteRule ^(?:application|modules|system)\b.* index.php/$0 [L]

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT]

```

The file is placed in the kohana directory. Apparently I'm only supposed to alter the RewriteBase variable, but I have no idea on what it should be
