.htaccess and subdomain folder

Question

my .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?my-site.com$ [NC]
RewriteCond %{REQUEST_URI} ^/my-subdomain/(.*)$
RewriteRule ^(.*)$ - [L,R=404] 

when I access to: http://my-site.com/my-subdomain/ it works, the folder is locked.

but when I access to: http://my-site.com/my-subdomain/img/101.jpg It does not work, I can access the image.

how can I deny the access to any image or image folder?

Answer 1

Those rules you have should work, make sure that your image isn't cached. Clear you cache and try again.

You can also consolidate your rules:

RewriteEngine On 
RewriteCond %{HTTP_HOST} ^(www.)?my-site.com$ [NC]  
RewriteRule ^my-subdomain/ - [L,R=404]
