How can I find the end address of a file?

Question

Computer networks

Screenshots of the video are located on the site, just below the download link. The link leads to a subdomain, there are no videos on the subdomain, only the script is stored on it. As I understand it, the id of the element or some kind of variable is passed to it. The variable contains the hash code. Where to go? How to find the way further?

Answer 1

The script on the server receives the hash code and generates a link that is valid for a limited amount of time (and possibly fenced with a cookie). You can see what kind of link it generates in the browser's "Downloads" menu.
