rpm -qv pykolab
pykolab-0.8.19-1.9.el7.kolab_16.noarch
I run the Kolab server in the standard version with http protocol.
This can be reached from the Internet via https using an HA proxy.
All requests that come via https are redirected to port 80 to the Kolab server.
During troubleshooting (files can only be accessed internally via http) I noticed that
http://mail.domain.de/chwala/skins/default/images/mimetypes/style.css
and
http://mail.domain.de/chwala/js/files_api.js
do not reply to https.
All other files run over https.
