      That is not true.
      While this may hold for searches, trying to access specific pages will give error messages.
      E.g. http://en.wikipedia.org/wiki/QWER
      gives "HTTP/1.0 404 Not Found"
      before starting a redirect.
      I assume that this would be the kind of link somebody might want to check using Xenu.

        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?
