I'm considering purchasing your File Attachments extension for a Joomla 5 website.
I intend to use it for distributing 3D CAD model archives (ZIP files) to website visitors.
I have three questions:
1. Does the extension generate temporary download links that automatically expire after a configurable period (e.g. 5 minutes), or are the download URLs permanent?
2. Does it support rate limiting to prevent automated bots from repeatedly requesting downloads?
3. Are the uploaded files stored outside the publicly accessible web directory, and are they delivered through a PHP download controller rather than direct file access?
These features are important because I want to protect the hosting server from automated mass downloads while allowing legitimate visitors unlimited access to different models.
Thank you!
