MIME Content Types

Software applications use content type headers to identify the type of data they receive. Content type
headers tell the software application how to correctly identify and display video clips, images, sound,
or other data. Usually, people are most familiar with the MIME content types used in email.
Some of the available proxy policies in your Firebox configuration can use content type headers to
determine whether to allow or deny traffic. This chapter contains a list of many common MIME content
types for your reference.
New, registered MIME content types appear regularly. We recommend frequent checks of an online
source for the most current list. One source of current MIME types is:
www.iana.org/assignments/media-types/
Note that software applications can use incorrect content types, or content types that are not
registered.
