I think you can write an upstream module to resolve it.
use the HEAD you get, to make a request, send the new request to the
upstream you want to sent, get the response, check it,
and then you can use ngx_http_internal_redirect（） function to redirect
the origin request to another upstream you defined.
just do it, good luck!
