Nginx levinstein for sub-domain

Question

Nginx

Just made a mistake when typing gist.github.com, gits.github.com. I was shown 404.
Is there a module for nginx that can collect information about domains from server_name/listen and check the most suitable ones for such cases, and redirect accordingly?

Answer 1

Do you really need it?

Answer 2

And how should this module behave in the case of the same distance (well, or some other metric) to two existing domains?
