DLM PDF.js System

Biophysics Lab’s DLM PDF.js System is a coordinated pair of WordPress proxies that deliver secure PDF viewing and protected file downloads with unified event tracking. Designed for sites using the popular Download Monitor and PDF.js Viewer plugins, this system ensures consistent file‑access control and accurate, consolidated activity reporting. It also demonstrates a practical, reusable developer pattern—leveraging trusted, rock‑solid plugins and extending them with lightweight “glue logic” implemented through Code Snippets.
