The problem you are running into is that SSL sessions are negotiated
prior to the browser sending the virtual host name, so there is no
opportunity to redirect the client to the www URL before it's too late.
 Aside from purchasing a second SSL certificate for the plain domain
name or getting a wildcard certificate to cover both, I would just make
sure the links on your web site to the secure version of the domain
specify the www in the URL.
