View domain statistics under https

[kclo]

We have created several domains under Plesk for Windows IIS. Each domain is shared on 1 IP only. For each domain, it allow users to view domain statistics under domain ftp account like

https://www.abc.com/plesk-stats/webstat
http://www.xyz.com/plesk-stats/webstat

However, it found that SSL can only support on 1 domain only. Other domain SSL can not turn on.

Any idea?

Thanks!
