This option allows you to specify the location where SSL certificates are stored. The meaning of this property depends on the SSL container class implementation. By default it just points to the directory where the server SSL certificates are stored in files in PEM format.

Default location is /certs however it can be changed using the following setting:

'certificate-container' {
    'ssl-certs-location' = '/etc/vhost-certs'

This replaces the former --ssl-certs-location property.
