return 404 from map module default value

[zflairz]

I think I need "location ~* ^/.+" instead of "location /" because I have
this:

        location / {
                index index.html;
        }

so www.example.com will read /index.html, while in the case of "location
/", it can't find / in mapping, then return 404. Am I right?
