Disable Ordinary HTTP

To disable ordinary non-encrypted HTTP, simply delete or move /etc/httpd/conf.d/secunia-csi-httpd.conf:

mv /etc/httpd/conf.d/secunia-csi-httpd.conf /tmp/secunia-csi-httpd.conf.obsolete

And then restart httpd to reflect the changes:

RHEL 7

systemctl restart httpd.service

systemctl restart haproxy.service
