The most insane issue with TrueNAS

This morning, I saw the login screen of my TrueNAS, so decided to have a look. After login, the TrueNAS rebooted...

This is really a design issue, both shutdown and reboot are not well designed, the URL can be reused without any warning prompt.

In fact, I knew this issue, but only careful enough just after reboot or shutdown performed. After yesterday's reboot, I didn't try to login using UI URL.

Although I careful enough, this issue leads me avoid using Back button of browser, because the URL can be in history.

The solution can be very easy, just change GET method to POST method in both reboot and shutdown pages with addition variable. But when will they make such change as it is already a mature product for years.
