Overview

Figure 1.  Example File Types Page

The File Types page (Fig. 1) allows you to manage Mako Guardian rules that ban specific MIME types and file extensions from being downloaded by users of the selected Mako.

Banned MIME Type rules prevent users from downloading a file of a certain content type, e.g. enter “video/quicktime” to block QuickTime videos.  MIME type filtering works on web servers that send MIME types, which includes most of the popular web servers.

Banned File Extension rules prevent users from downloading a file with a certain file extension, e.g. enter “.vbs” to block Visual Basic scripts.
