Univention - can it run as website server?

Univention have any WWW server extensions? Can it be used that way? If it can, what about security for huge pages with really big databases? For example like this: zoptamo.com/uk/s-boxing-c-uk-coach so marketplace which means high rate of variable of users entries . Can it be secure from now popular DDoS on Univention?

Univention’s Corporate Server comes with apache2 which you might configure to host several virtual hosts. Due to this is possible it is not intended, UCS doesn’t look like a typical webserver. Probably - if you really need the benefits of the UCS’s LDAP functionallity - you should use another (maybe debian or rhel based) server, join that one to your domain and let that specific machine do the web-thing for you.
