SSL - can you insite on having certificate?

If you connect to an SSL secure site that does not have a certificate
from one of the big CAs, or the certificate has expired, you get asked
if you will accept the certificate or not.

I implemented an SSL site at

https://www.3gshare.info/

which is for private use, so such messages are not an issue.

However, is it possible to configure the site such that unless you have
already have a certificate on your machine, you are unable to connect?
i.e the user has no choice to accept it or not - they either have it, or
they can't connect?

I don't think this is possible, but if it is, please let me know how.
The server runs Apache 2.x.
