Anything wrong with a URL structure like:
www.mysite.com/process/widgets/red-widgets
Where the DIR: /process/ is completely empty e.g. you get a 404 if you go to www.mysite.com/process/ and it has no content within.
This URL structure was setup before they knew what SEO was...wondering if it's worth the pain the 301 and restructure new URLs or is it ok to leave as is?
