At first, thank you for great plugin! :)
My problem: The javascript "pdf.min.js" is making a GET request that reveals the URL to the uploaded PDF from which the FlipBook is made of. It means any user can copy this URL and directly download the underlying PDF. No matter if I disable the saveCMD in the settings. Is there a possibility you can update the request, to be at least harder to read. Or is there a possibility for protecting a PDF from direct download on a server, but allow only the plugin to download it? I tried "Prevent Direct Access" plugin, but after protecting the PDF file, neither the 3D FlipBook had access to it.
Thank you for your help in advance!
Use an access plugin to deny access such as publishpress permissions. You can then limit access to the pages and the file.
If I limit access to the file (what I need) how I allow acces to tyhe file only for the FlipBook?
open the pdf first in flipbook before protecting it, then once processed in flipbook, then protect original file. It works fine for me.
plugin require access to PDF to fetch data, if you want to protect it - you can convert PDF to images.
