force or remove trailing slash: duplicate cache issue

[eluser]danoph[/eluser]
I've been looking for a solution for a while now, and this one works perfectly on my mediatemple server hosting http://graphicleftovers.com (built in codeigniter + wordpress for blog), as is without any editing:

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    # this adds trailing slash
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_URI} !(.*)/$
    RewriteRule ^(.*)$ $1/ [R=301,L]

    # this gets rid of index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1

</IfModule>

Thanks a lot @mania!
