Hi, the second option seem interesting and relatively "simple" solutions, but I am having some problems.

I put a pdf file in the domain.com/assets/file/test.pdf directory

I created a cookie when a user logs in.
document.cookie = "user_logged = 1";

On Nginx I created this rule:

location ~ ^/assets/file/ {
if ($http_cookie ~* "user_logged") {
allow all;
}
root /path/to/root;
}

I also tried this:

location ~ ^/assets/file/ {
if ($cookie_user_logged = "1") {
allow all;
}
root /path/to/root;
}



But it seems not to work correctly, the user either manages to download from the direct link https://domain.com/assets/file/test.pdf from the browser,
and from the a href tag of the site, or fails from either side.
