// This example demos serving HTTP on your tailnet.
//
// To run entirely locally use:
//
//	go run ./example_httpts.go -devport 8080
//
// This is useful for local development on the bus.
// To run on a tailnet, drop the -devport flag:
//
//	go run ./example_httpts.go
//
// The first time, a tailscale login URL will be printed to put it on a tailnet.
// Then it will print out the full URL of this server.
