Recently displayed documents are automatically added to cache, so that subsequent document requests can be processed faster. Documents are cached on the server when loaded for the first time. If a user tries to view a document that is already in cache, it loads much quicker. And thanks to the AOT (ahead-of-time) caching, you can add certain documents to cache manually, before they are requested by users.
If you don't want users to download an original file, but still want to share the document with them, you can either disable the download option, or set the viewer to automatically convert the shared document into PDF format. With this option enabled, the original file hosted on your server stays intact, and users only get a PDF copy when trying to download it.
The documents you display can be protected with text watermarks. Watermarks are rendered above the document on the client side only, the original file hosted on your server is not modified.
