      There are a couple of thousand users using Xenu if they all started
      sending requests to wikipedia site then the server soon gets bogged down
      trying to deliver the pages. Its the same as those people using website
      copying software. I have had my photography gallery go very very slow at
      times just because someone is trying to hoover up the pictures.

      What would be nice is to find out from wikipedia what changes need to be
      made to Xenu so make it nicer to their systems. E.g some sort of delay
      when getting pages from wikipedia servers.

        Xenu is already "nice", i.e. it makes a HEAD request, not a GET request.
        My opinion is that the wikipedia software is crappy. The organisation is
        mostly concentrated on collecting money, enforcing censorship, altering
        history, and being busy with itself (many of the admins are just very
        intelligent kids with too much time), instead of delivering a high
        quality product by running a Continuous Improvement Process.

          There are plenty of old admins, I can assure you :-)
          The software is probably rough - it *is* still a charity, and due to the
          mindless antics of loads of juniville vandals, it needs a large team of
          vandal fighters (not just admins - there's only 1000 regular ones) to keep
          the pages more or less intact - English Wikipedia has around 150-200 pages
          change per minute, and around 10% of those have to be reverted - so the
          servers are already very busy, and I think allowing Xenu in will grind it to
          a halt - If the Dutch mirrors go down, and I have to connect direct (from
          UK) to the USA servers, then it can take 30 seconds plus for a medium page
          to load.

              On my local hard disk I have a folder containing hundreds of html files,
              and an index.html file that contains links to all of them.

              When I run xenu on the index file, it correctly reports no broken links,
              but it also reports that all of the other files are orphans.

              Why is this? What am I doing wrong?
