Plesk 12.x / Linux :: Standard Domain Forwarding Does Not Forward Https Connections

URL....We are running Plesk 12 on a Linux VPS where we have multiple domains running.Multiple of these domains should redirect from www. domain name. ext to https://ext.domainname.com.This is configured with the Domain forwarding in Plesk, with hosting type Forwarding.But as described in the 2 links provided above, whenever you go to https://www.domain.ext, it does not redirect, and actually shows a Security error, since the domain doesn't have the SSL-certificate installed (because it should redirect to the https://ext.domainname.com).

Clearly we don't want visitors on the website to receive the (incorrect) Security error, and we want all traffic to http(s)://www.domain.ext to be redirected to the appropriate subdomains. allows us to redirect both the https/http connections to the domains, without forcing us to have the domains have a Website hosting add redirect them manually with (for example) .htaccess.
