I have developed a custom 404 page that analysis the url and other request variables to determine where to redirect (301) the user.
The logic is kept in a data file (xml) so I can easily update these "mappings" as I find the need.
I developed this because the site I inherrited had already gone through several re-writes, where the old pages were the ones indexed in all the search engines. There were over 1000 obsolete pages indexed when I started.
