i couldn't get thru the wall of boring PDF text, but is this a scheme to checksum an url, then send the code with the request, so the webserver can 404 if the user altered the url?

absurdistan•2h ago

Yes, along with incorporating into the checksum any other session data the server desires. Basically, DRM for links.
