Full and Partial Content Blocking VIA htaccess file

First create a .htaccess file

Code:

sudo gedit .htaccess

Full Blocking Method (prevents even playing content and direct access)

Code:

<Files ~ "\.mp4$">
  Order allow,deny
  Deny from all
</Files>

Another Better Method (better as it allows content to play) Blocks direct access!

Code:

RewriteEngine On
RewriteCond %{HTTP_HOST}@@%{HTTP_REFERER} !^([^@]*)@@https?://\1/.*
RewriteRule \.(gif|jpg|jpeg|png|tif|pdf|wav|wmv|wma|avi|mov|mp4|m4v|mp3|zip?)$ - [F]
