Myar on "rewrite rule for ?tag=&category_name="

Hi!

I need the rewrite rule for htaccess, to get mydomain.de/apple/fruits from mydomain.de/?tag=apple&category_name=fruits

I want to build some tagsites as topic pages and style them indivudally and have a summary of excerpts of some categories and build a menu to the categories with post with the explicit tag.

For this existing rules:

ModPagespeed off
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I hope you understand waht I mean, I'm not so good in english ;)
