[Cialug] SSL & private key ?

[albus]

To start off heres the background

1. I created a private key as root in the users dir.
2. I generated the csr in the users dir.
3. I have the cert installed in the users dir and https all works for the site.

Now the question.

When I go to do another sites SSL cert. does the server
use the same private key for all requests?

Info:
Apache server with openssl and mod_ssl.
