apache - configure only allow specific domains to access certain folders using .htaccess

Question

I am having a scenario as following:

For example,I have a website http://www.example.com, and I have setup a few subdomains such as http://video.example.com, http://image1.example.com, http://image2.example.com. In Apache virtual host setting, they are using the same folder (e.g. /home/example/). (these two domains have different bandwidth setup using mod_cband).

I have a subfolders /home/example/files/videos, I want to make it only accessible from the subdomain http://video.example.com/files/videos/ but not from http://www.example.com/files/videos/ or any other subdomains.

How shall I configure this with a .htaccess file?

Answer 1

Put this code in /home/mywebsite/files/videos/.htaccess

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /files/videos/

# if it is not for domain video.mywebsite.com then block it
RewriteCond %{HTTP_HOST} !^video.mywebsite.com$ [NC]
RewriteRule ^ - [F]
