Also I want to replace typcal mongrel configuration:

  location / {

      if (-f $request_filename) {
          break;
      }

      if (-f $request_filename/index.html) {
          rewrite (.*) $1/index.html break;
      }

      if (-f $request_filename.html) {
          rewrite (.*) $1.html break;
      }

      if (!-f $request_filename) {
          proxy_pass http://mongrel;
          break;
      }
  }

with something like

     location / {
         match  $request_filename
                $request_filename/index.html
                $request_filename.html;
                @mongrel;
     }

like "index" directive.

Or

         try    $request_filename
                $request_filename/index.html
                $request_filename.html
                /some_fallback_url;
