MIME types relay information to the browser about how to handle file extensions. Adding MIME types is useful for enabling visitors’ browsers to handle new technologies as they come out. cPanel lets you add new MIME types to your web server by defining a name, directory, and corresponding file extension.
To add a MIME type:
1. Enter the name of the file type’s handler into the "Mime Type" field. For example, "application/cgi" would be the handler for the .cgi extension.
2. Enter the file extension in the "Extension(s)" field.
