When running ZABBIX GUI with a HTTPS-only web server, the sorting of items (e.g. in Configuration section) will not work because the sort links are created using "http://" prefix.

To reproduce:

• Set up ZABBIX GUI in a HTTPS virtual host
• Disable any non-encrypted HTTP access
• Go to "Configure -> Hosts"
• Click on any of the table headers for sorting
• Get 404 or connection refused, depending on your web servers configuration (because the link points to http://server/hosts.php instead of https://server/host.php)

How to fix:

• See patch below (it's not shttp but https, and the right way to detect the protocol to use is evaluating _SERVER['HTTPS'], the "SERVER_PROTOCOL" will always be HTTP/1.x
