Disabling Script Execution in a Directory in IIS7

Last night I was trying to disable script execution in the uploads folder of a site running in IIS (Windows 2008).  It is also running ColdFusion, which turned out to be important.  I ran into a couple problems.

The first was that I had no idea how to do that in IIS7.  I knew how to do it in IIS6, but everything is different in IIS7.  I thought I would be able to just find it, but after poking around for a while, I gave up and ran to Google.  Turns out the new location to set this is in Handler Mappings.  If you go to the Handler Mappings feature for a directory and click on "Edit Feature Permissions...", you can uncheck the "Script" permission.

So I did that, and I thought I was done, but then I noticed that not only could I not run scripts from the directory, but trying to access a static file, such as a gif, also gave me a "403 Access Denied" message.  Strange.

It turns out that ColdFusion installs a wildcard script map, which means that it is set up to handle all files, even static ones.  I don't know what the reason for this is (and I would love to find out if anybody knows), but it was getting in the way of the default static file handler.  I had to remove that handler for the directory in order for the static files to be served properly.
