Apache目录问题，将请求重定向到index.php

I have a joomla website.

In my public_html where Joomla is installed, I have a directory named "logs-list".

When I go to the address http://example.com/logs-list/file.txt, I expect the file to be shown, but instead APACHE redirects to index.php, it assumes as if this is a request for Joomla. This has confused me. What should I do?

UPDATE how I can tell in .htaccess to stick to the physical directory for a certain URL?
