I have an application which allows clients to upload various files which 
can later me accessed via the web. My concern is that if the uploaded file 
has a .cfm extension, when it is reviewed post upload, it could actually 
execute malicious code on the server. I guess the same would hole true with 
a .exe file (except that execute privileges are disabled).

I need to allow a wide range of acceptable upload types, so I can't 
restrict it at the upload stage. What would be the best way to allow some 
one to access these files post upload while not posing a security threat?

How would I enable a download of a .cfm file or a .js or whatever without 
having it execute on the server as opposed to promoting for a download?
