In the HTTP protocol a 404 Error is returned in the header, your return
might look like this...
HTTP/1.1 404 Not Found

This subject came up before, but I don't know if a definitive answer was
ever given. Obviously, you will need to use CFHTTP to connect to all the
links, but that's where things get hairy. Since many sites customize their
404 error pages, determining whether the resulting CFHTTP content represents
a 404 error or not is very difficult.
You could probably loop through all of the links and flag those that may be
404 errors and then have an employee manually check them. This would give
you the greatest degree of certainty but would also cost manpower.
