password .htaccess

Good morning everyone, so I'm setting up a movie server and I have several movies in a vps and my site is hosted on the hostgator. Is it like for a password with .htaccess in my vps and do authentication with the post method? Why before I get the movie I would send a post from my site to vps, if the communication between the site and vps was all okay I would reproduce, otherwise I would not reproduce.
