IIS Redirects not working with CF11

Hi, our IIS Redirects are not working with CF11.  IIS 8.5 (on Win2012) redirects work fine only if there are no ColdFusion files specified in the URL. The redirects are specified to redirect to a specific URL, to redirect to the exact destination, and to send an HTTP Response code of 301 Permanent Redirect.

However, with a .cfm file on the URL, the response is "The page cannot be displayed because an internal server error has occurred." The HTTP Response Code is 500 Internal Server Error. The web logs shows it as a 404.0 File Not Found error.

If we add the 'missing' .cfm file, the .cfm file gets processed ... thus, there is no redirect. It seems that the Connector is taking over before IIS can respond and process the Redirect.

Any ideas?

thanks,

Chris
