A most powerfull way is to use the new feautures included in apache 1.3, the
possibility to define a Virtual Host NameBased.

On my machine (192.168.2.2) i have defined this two virtual host:

"httpd.conf"

    ...
    NameVirtualHost 192.168.2.2

    <VirtualHost 192.168.2.2>
    # primary vhost
    ServerAdmin webmaster <email protected>
    ServerName home.first_domain
    ServerAlias *.first_domain
    DocumentRoot /usr/local/apache/share/htdocs
    </VirtualHost>

    <VirtualHost 192.168.2.2>
    DocumentRoot /usr/local/apache/share/home.second_domain
    ServerAdmin webmaster <email protected>
    ServerName home.second_domain
    ServerAlias *.second_domain
    ServerPath /home.second_domain/
    RewriteEngine On
    RewriteRule ^(/home\.second_domain/.*) /usr/local/apache/share/$1
    </VirtualHost>

So , when you try to connect to home.first_domain the apache server , serve
pages in /usr/local/apache/share/htdocs and when you try to connect
home.second_domain apache serves the pages in
/usr/local/apache/share/home.second_domain.

The ServerPath is needed because 'there are still some clients in use who do
not send the required data for the name-based virtual hosts to work properly.
These clients will always be sent the pages from the primary name-based
virtual host (the first virtual host appearing in the configuration file for
a specific IP address).' (From the Apache 1.3.0 manual)
