I am working on a hand full of projects where I dont want to send people that come in off search engines to 404 pages. So I wrote a module this weekend that will take the 404 info (as seen in my other blog about how to create 404 pages), and redirect them to the correct page, without them even being bothered by a notice telling them the file is not found.
It was a very simple module (as I expected), and so far it looks and works good. Now I just have to do the hard part... create all the redirects. I am thinking I will extend the module to record links that were not handled, so mappings could be easly created for them.
Update: This module is available for purchase on SnowCovered ( http://www.snowcovered.com/Snowcovered2/Default.aspx?tabid=242&PackageID=7640 )
