   Just added Web Reachability API (at least that’s what I’m calling it) support to https://ip.small-web.org.

   It’s for testing the reachability of your Small Web servers (using a domain or, more importantly, an IPv4/IPv6 address). I’m using it to implement Web Numbers¹ support in Auto Encrypt² and Kitten³.

   Protocol:

   • At http://<endpoint> return an empty HTTP 200 response that includes the following custom header: 'web-reachability-id': ‘<uuid>'
   • Hit: https://ip.small-web.org/reach/<endpoint>/<uuid>/
   • If you get a 200 response back, your endpoint is reachable. Anything else signals an error.

   Enjoy! 💕
