Content Types
CHAPTER 2
A content-type header is used by applications to determine what kind of data they
are receiving, thus allowing them to make decisions about how it should be handled.
It allows clients to correctly identify and display video clips, images, sound, or non-
HTML data. People are probably most familiar with the MIME content-types sent in
e-mail.
The WatchGuard Proxied HTTP service uses content-type headers to determine
whether to allow or deny an HTTP transaction. Use the Policy Manager to configure
the Proxied HTTP service to allow or deny content-types. Content types are also used
in SMTP and are configurable in the SMTP proxy. This chapter contains a list of the
more commonly used MIME content-types. The MIME content-types are written as
follows:
type/sub-type
Wildcards may be used to select all sub-types within a type, thereby denying all or
allowing all of that MIME type. For example, to allow all content-types that are text
(including text/enriched, text/plain, and others), use the content-type
New, registered MIME content-types appear regularly. WatchGuard
recommends frequent checking of an online reference for the most current list.
One source of current MIME types is

In addition, WatchGuard encourages you to e-mail requests for inclusion of new
