问题
I just got a custom handler set up to redirect with a 301 response for some old coldfusion page references that I have on my new mvc 3 site. The problem is, I have to actually have the .cfm files on the server for the handler to take effect. If they're not there, my customerrors element is taking over and doing a 404 redirect...when the files are there, works like a peach. My issue is that I'd have to create a boat-load of empty files for the handler to grab them and I'd like for it to just work w/o having the file physically on the machine.
....is this possible? Does the customerrors element always take precedence? Is there a way to override that?
here is my handler node:
<add name="ColdFusionRedirect" path="*.cfm" verb="*" type="MySite.Services.ColdFusionRedirect, MySite" resourceType="Unspecified" />
Edit: it turns out it's not the customErrors node that's taking over, my handler just flat out doesn't work when there is no file...I still get 404s. How can I make this call my custom handler even when files don't exist?

You want to add this to your global.asax RegisterRoutes method:
routes.IgnoreRoute("{resource}.cfm/{*pathInfo}");
