How to correctly organize the distribution of files?

Question

Data storage

Connoisseurs, advise how to be. There is a site with ~10000 visitors. It will contain links to download archives (zip, rar...). The main site is located on the same hosting, the files are in the cloud storage of another hosting provider, the sites are not directly connected to each other. Cloud storage is static, no dynamics. How to combine them?
The sequence of actions when receiving files: the user enters the main site, clicks the link, the anti-leech script processes the request and gives a link to the file from the cloud storage, while not revealing the real address of the file storage. Purpose: to prohibit receiving files directly from a remote cloud storage without visiting the main site located on another server. Is it possible to organize this using, for example, php?
Sorry for the broken explanation )) I just don't even know how to approach this issue ))
