How to add/delete mime type in cPanel

MIME types (Multipurpose Internet Mail Extensions) relay information to the browser about how to handle file extensions. MIME types can allow visitors’ browsers to handle new technologies as they become available.For example you can add the extension .cgi of MIME Type — application/cgi to be handled by the browser.

In other words ,MIME type tells browsers how to handle specific extensions. For example, the text/html MIME type equates to .htm, .html, and .shtml extensions on most servers, and this tells your browser to interpret all files with those extensions as HTML files. 

The Internet Assigned Numbers Authority (IANA) is responsible for all official MIME types, and you can find the most up-to-date and complete list at their Media Types list page.

In addition you can alter or add new MIME type specifically for your site . MIME types are often used to handle new technologies as they appear. When WAP technology first appeared no one had these extensions set up on their server. With MIME types, however, you could have set it up yourself and begun serving WAP pages immediately.
