Replay protection

The module's client area actions are protected by a no-replay token. This is automatically appended to action URLs. This prevents the end user from bookmarking the shutdown URL and shutting their VM down every time they view it in their client area via their bookmark.

WHMCS does not protect module actions by default, so be aware that a page can't be refreshed to re-run an action on a VM, which may be possible with other modules. For more information see this issue.
