The large-document.json profile
File: media/plg_system_wtpdfjs-config/large-document.json. Range enabled, streaming and prefetch disabled. The server must support byte ranges and correct 206/Content-Range. PDF.js still requests data for structure, fonts, pages and search; this does not guarantee downloading only one page. A full download may occur without Range support.
