Apache2 to lighttpd, confused squirrel needs advise

[squirrel]

Hi,

I'm totally new to lighty (Apache user) and I need some help. I would
like to have something like that:

NameVirtualHost xxx.xxx.xxx.xxx:80

<VirtualHost xxx.xxx.xxx.xxx:80>
 ServerName domain.com
 ServerAlias [url]www.domain.com[/url]
 DocumentRoot /var/www/user/folder/
 <Directory "/var/www/user/folder/">
 Options -Indexes Includes FollowSymLinks
 AllowOverride All
 Allow from all
 </Directory>
 Options +FollowSymLinks
 RewriteEngine On

 RewriteCond %{REQUEST_URI} !^/wiki2(/.*)?$ [NC]

 RewriteRule ^/$ [url]http://www.domain.com/wiki[/url]
 ProxyPass /wiki [url]http://www.domain.com:8082/wiki[/url]
 ProxyPassReverse /wiki [url]http://www.domain.com:8082/wiki[/url]

 ProxyPass /wiki2 [url]http://www.domain.com:8082/wiki2[/url]
 ProxyPassReverse /wiki2 [url]http://www.domain.com:8082/wiki2[/url]

 ErrorLog /var/www/user/error.log
 TransferLog /var/www/user/access.log
 CustomLog /var/www/user/combined.log combined
</VirtualHost>

How can I achieve that in lighty? I tried to understand (really!) the documentation provided by lighty, but they are very confusing to me.

Any help is much appreciated (sorry that it's not quite a Kubuntu topic...)!

Cheers,
Squirrel
