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
