Is the custom 404 errors set in the IIS or ColdFusion? One of our read only production server is not displaying the custom 404 error and I like to find out why. Any suggestion is much appreciated.
The answer is "both."
It depends on the handler of the URL received by IIS.
For example, if you request a nonexistent .HTM file, IIS will handle it. If you request a nonexistent .CFM file, ColdFusion will handle it.
