Title: How to Remove a MIME Type from a Web Site in IIS in Windows Server 2003

Objective: The objective of this demo is to teach you how to remove a MIME type from a Web site in IIS in Windows Server 2003. Multipurpose Internet Mail Exchange (MIME) types instruct a Web browser or mail application how to handle files received from a server. For example, when a Web browser requests an item on a server, it also requests the MIME type of the object. Some MIME types, like graphics, can be displayed inside the browser. Others, such as word processing documents, require an external helper application to be displayed. IIS is preconfigured to recognize a default set of global MIME types. These MIME types are recognized by all Web sites you create in IIS.
