The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)
It does not balance, it leaves it to the kernel.
In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)
I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one

example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
