There are still a lot of URLs in search engines that refer to old pages
and I'm trying a new method to get them removed from search results. This means,
that I do not redirect 404 errors as 301 errors to the new location as no search
engine seems to update their indexes with the new URLs. The negative effect is,
that you have to search the updated URL by hand.
