Redirect loops and mazes

[Sean Conner]

It was thus said that the Great solderpunk once stated:
> One downside of Gemini's support for redirection is that poorly

> infinite loops of redirects, or just lead clients on long chains of many
> consecutive redirects.  High quality Gemini clients should be able to

  Already done.  It took more time to write up the test page than it was to
write the code, which is just three lines:

function handler(_,_,loc)
  return 31,uurl.toa(uurl.merge(loc,{ path = tostring(uuid()) })),""
end

  And speaking of tests, have you finished the Gemini server torture test?
