    Virtual host examples from Apache website.

    http://httpd.apache.org/docs/2.0/vhosts/examples.html

    Turns out that it is possible to have multiple VirtualHosts on port 80 (Default http), but because of a limitation of SSL, we can’t have multiple VirtualHosts on port 443 (Default https).
    I solved the problem as follows. I created the two VirtualHosts on port 80, one on port 443 and one on port 444.

    Shared IP, multiple vhosts and multiple SSL certificates on Apache

    The process is only 2 steps and involves modifying your Apache configuration.
    1.  Create virtual hosts “map file”.
    2.  Modify existing SSL vhost.

    Caveat: The SSL certificate used will be common to all SSL vhosts.
