Topic: 2nd SSL certificate for subdomain

[Mumm-Ra]

I know I can't add a certificate for a virtual domain but I want to add a certificate for a subdomain of my primary domain.

My server's name is mail and I have a SSL certificate for that working fine i.e https://mail.mydomain.co.uk but I want to register a certificate for www too i.e https://www.mydomain.co.uk

Whenever I customise the 35SSL10SSLCertificateFile fragment and then restart the httpd service I end up with errors.
Can I do this?
