Description

The Block Hotlink addon prevents files hosted via Download Manager from being downloaded from directly copied links on external sites, validating the referrer of the request before releasing the file. This component protects bandwidth and access control to your library, ensuring downloads occur only through pages of the site where the package was published.

Main Features

  • Referrer Validation: checks the origin of the request before serving the file, blocking access from external domains.
  • Direct Link Protection: prevents download URLs pasted in forums, blogs, or social networks from delivering the file to third parties.
  • Integrated Admin Setup: adds specific options within the Download Manager panel, without requiring manual server rule edits.
  • Allowed Domain List: allows you to set which origins can serve downloads, useful for multisites and authorized partnerships.
  • Compatibility with Existing Packages: applies to already registered downloads in the library, without needing to recreate files.

Benefits of Block Hotlink

  • Bandwidth Savings: reduces consumption from unauthorized access pointing directly to your files.
  • Distribution Control: ensures content is delivered only within the context of your download page.
  • Metric Preservation: keeps download counters aligned with real visits to your site.
  • Monetization Reinforcement: makes it harder to divert traffic to download sites on third parties that copy your links.

Who Is It For?

  • Digital library administrators who distribute PDFs, images, videos, or software packages.
  • Membership sites, courses, and restricted areas that need to secure paid files against external sharing.
  • Publishers and editors who rely on visits to download pages for generating revenue and metrics.

Aimed at those who use Download Manager as the backbone of file delivery, Block Hotlink closes one of the most common gaps in this flow: copying the final download URL outside the site. By conditioning delivery on the request’s origin, it keeps traffic, access counts, and added value of pages concentrated on your own domain.
