apache: define multiple domain over http & https

to define multiple domain, make sure you include NameVirtualHost setting and <VirtualHost> entries in your apache configuration file.

i got the ff warning messages when i forgot to include these settings:
[] [warn] VirtualHost 127.0.0.1:443 overlaps with VirtualHost 127.0.0.1:443, the first has precedence, perhaps you need a NameVirtualHost directive
[] [warn] _default_ VirtualHost overlap on port 443, the first has precedence


here's what i have in my apache configuration file for multiple domain handling over http and https:
# this is important to handle different domains and ports
NameVirtualHost *:80
NameVirtualHost *:443

<VirtualHost *:80>
        ServerName mydomain1.ph
        ServerAlias www.mydomain1.ph
        DocumentRoot /usr/local/apache2/htdocs/
</VirtualHost>

<VirtualHost *:80>
        ServerName mydomain2.ph
        ServerAlias www.mydomain2.ph
        DocumentRoot /usr/local/apache2/htdocs/mydomain2
</VirtualHost>





<VirtualHost *:443>

        ServerName mydomain1.ph

        ServerAlias www.mydomain1.ph

        DocumentRoot /usr/local/apache2/htdocs/

        SSLEngine  on

        SSLCertificateFile /usr/local/apache2/conf/ssl.crt/server.crt

        SSLCertificateKeyFile /usr/local/apache2/conf/ssl.key/server.key

</VirtualHost>




<VirtualHost *:443>

        ServerName mydomain1.ph

        ServerAlias www.mydomain2.ph

        DocumentRoot /usr/local/apache2/htdocs/mydomain2

        SSLEngine  on

        SSLCertificateFile /usr/local/apache2/conf/ssl.crt/server.crt

        SSLCertificateKeyFile /usr/local/apache2/conf/ssl.key/server.key

</VirtualHost>
