What I'd do instead is leave enough breadcrumbs here in the text - doc ID, doc title etc, so that people can actually find the document by using a search engine which has managed to index it. Instead of updating links mindlessly because those do change constantly. No matter the vendor - as long as it is a corporate website, links get changed on a regular basis. I'd say. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
