I've uploaded woff and javascript files that have been minimised (hence xxxx.min.js) to a media library but Kentico is unable to serve any of these files to the browser when the site is viewed. Kentico will serve the other file extensions but as soon as a .woff or .min.js file is requested, a 403 - Forbidden error is thrown to the user instead.

I suspect it's the http handlers trying to so something with the files but nothing actually needs to be performed. I have allowed all files to be uploaded to the media library but I don't know what other setting I'm missing.
