Can't protect a folder using python script

Hi
I am trying to protect a folder: /home/nginx/domains/mydomain.com/public/folderx/

I just run:
python /usr/local/nginx/conf/htpasswd.py -c -b /usr/local/nginx/conf/htpasswd admin passwordx

Then i edit the vhost file of my domain: /usr/local/nginx/conf/conf.d/mydomain.com.conf
and i try to add this inside:

---

auth_basic "Private";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;

This protect my site and not the folder...

It seems that this is normal as i add it on:

location / {

So i create another location under the } of the above code like:

location /home/nginx/domains/mydomain.com/public/folderx/ {
auth_basic "Private";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}

save and restart but doesn't work again
What i am doing wrong?
On both cases i was restart nginx and then test.

I got the info from here:
Nginx and vBulletin Connect 5 Vhost

Thanks

 

Ok i add this:

location /folderx/ {
auth_basic "Private";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}

Then i restart the nginx and again i can open the file.php inside the folderx
I tested on another browser also...
