Setting access by headers in htaccess apache 2.2 windows?

Question

Apache HTTP Server

Colleagues, good afternoon!
I'm learning how to protect direct links to Apache. The situation is as follows, there is a page localhost:81/site/page1.html, on which a video is played in the tag at the link localhost:83/video/v2.mp4
I tried to set up the following .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !.*/*\.html$
RewriteRule \.(mp4)$ localhost:81/page1.html [R=301,L]

The idea was this: when opening a direct link, it redirects to page1.html
However, it does not redirect, when a direct link is opened, the video does not really play, but it can be downloaded.
On the network tab, I see the following.


Could you tell me how to configure htaccess correctly?
