The Mime Types Manager will allow you to add new Mime types to your site. MIME stands for Multipurpose Internet Mail Extensions, which is an official Internet standard that specifies the way in which information must be formatted. Originally used just in email, MIME types are now used by many applications. Your browser uses them to determine what application should be used to open and/ or edit files.
Incorrect MIME settings are one of the most common sources of HTTP Error 405.
