I have been beating my head against this problem for quite a while now. I am trying to configure IIS on windows 8 with coldfusion 11 on my local machine for development purposes.
Basically, I want 404 errors to be caught by Coldfusion and handled by that. These requests have and extension that ends in ".cfm". I have SES(search engine safe) urls for non existent product pages that are handled by the app and resolve to product pages. All I get is IIS's 404 page. I should not have to configure a custom 404 page handler and the passthrough option does not work; all I get is a blank page.
Thanks.
