Show PDF only for registered customers

If you load a PDF, for example a price list or an order form, onto your web space and link to it in the content, then guests who know the link and - even worse - search engines can access it.

We therefore query in a script whether the viewer is a registered customer of customer group XY and only then allow him to see the PDF document.

Of course, we can't prevent them from taking photos of it or saving it. But at least the documents do not end up in search engines.
