Howdy, internet stranger!
This is a demo of Tailscale's identity headers. You can add this machine as a "shared node" to your tailnet and see how it can serve different content based on those headers. It will only be visible to you—not other users on your tailnet—and will not be able to initiate connections to any of your devices.
To add this node to your tailnet, click this invite link and log in to Tailscale.
