Name based virtual hosts aren't working

Hi!

I want to do the following:

Register a domain, add several CNAMES to my DNS and make Apache load files from different directories based on the url name.

So I've created a file for virtual host configuration in directory "sites-available". Then I include it in apache2.conf:

# Include the virtual host configurations:
Include /etc/apache2/sites-enabled/

Code (markup):

Configuration file looks like the following (the complete content is attached):

<VirtualHost *:80>
        ServerName coolbox.org.ru
        ServerAlias coolbox.org.ru *.coolbox.org.ru
        DocumentRoot /var/www
</VirtualHost>
...
<VirtualHost *:80>
    DocumentRoot /home/testuser/www
    ServerName  testuser.coolbox.org.ru
    ServerAlias testuser.coolbox.org.ru *.testuser.coolbox.org.ru
</VirtualHost>

Code (markup):

My domain is not ready yet, so I try to test it by editing hosts file in my Windows system (my real IP instead of 123.123.123.123):

123.123.123.123 www.coolbox.org.ru
123.123.123.123 www.testuser.coolbox.org.ru
123.123.123.123 www.HiDaN.coolbox.org.ru
123.123.123.123 www.coder11.coolbox.org.ru

Code (markup):

My problem is only one of the urls works fine (Apache takes files from the right directory). Others "leed to" the first entry (DocumentRoot /var/www). Changing the order of hostnames in hosts file affects nothing. Changing the virtual hosts orders causes another url to work fine while others still "leed to" /var/www

Any Ideas how to solve this?

Regards.
