Well, the idea is to set your root dynamically from the default
server block depending on the 'host' header.

You can either use $http_host as a part of your root, which
is probably not a good thing, or map it to some subdir, and
use its value instead:

    map $http_host $subdir {
        default "default";  "foo";  "baz";

    server {
        root /path/to/$subdir;


Hope this helps.
