I have a few video files uploaded and i’m using that video URL in other website to play that video, is there any way to protect that video files so if someone inspect and find the video URL and when the goto URL they will redirect to some other page or give them an error, is this possible with virtualmin?
Has nothing to do with Virtualmin. Virtualmin isn’t your web server and has no interaction with website users.
You could configure the web server or your app that is serving the video to reject requests without the right Referer header. This can be spoofed, but it will stop casual downloaders.
