Overview

MIME types 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.

To add new MIME types to your web server, define the name, directory, and file extension that correspond to the MIME type.

Create a MIME Type

To add a MIME type, perform the following steps:

1. Enter the name of the file type’s handler in the MIME Type text box.
   • For example, application/cgi represents the handler for the .cgi file extension.
2. Enter the file extension in the Extension(s) text box.
   • A file extension represents the letters after the dot (.) in a file name. For example, filename.fileextension.
3. Click Add.

Delete a user-defined MIME type

To delete a MIME type, click the corresponding Delete link under the Remove heading, and then click Delete MIME Type to confirm that you wish to remove the MIME type.

More about MIME types

For more information, read the Webmaster Toolkit list of MIME types. You can also use your preferred search engine to research the MIME type that you wish to add.
