Can we browse another drupal installation in subdirectory of a domain?

Hi, Im not Nginx user, but I need to ask before setting up nginx for my drupal website

I need to have my domain.tld running, which means in the domain.tld folder is Drupal installation.

So I will see my website when I browse http://www.domain.tld/

But I have a folder with name "app1" which contains another Drupal installation.

So I will see another Drupal installation when I browse http://www.domain.tld/app1/

I dont want to setup subdomain because this way is far easier and dont need other codes in config file.

This works fine in Apache2, but not works in lighttpd

But how about Nginx, is this works in Nginx?

Thanks.
