Blank Pages in CF10 for .CFM (uppercase only) pages

Question

We have multiple servers with IIS7 and ColdFusion. Some are CF9, some are CF10. Coldfusion pages ending in ".cfm" (lowercase) render correctly on both. However, if you type in ".CFM" (uppercase) as the browser url, the Coldfusion 10 servers return a blank white page. (page source is empty also) The Coldfusion 9 server renders the page normally. Any ideas on how to fix this?

Answer 1

Coldfusion 10 is supposed to be case sensitive when it comes to file names.

Answer 2

ColdFusion 10’s built-in Tomcat web server handles case sensitivity different than the old JRun built-in web server. Basically, it follows the RFC and is case sensitive.
