Add downloadable file types in IIS6

using MIME type


Multipurpose Internet Mail Exchange (MIME) types of documents illustrate how the Web browser or mail application process received from the server. For example, when a web browser requests an item on the server, it also requests the MIME type of this object. Some MIME types (such as graphics) can be displayed inside the browser. Other MIME types, such as word processing documents, need to be displayed using an external help application.

When IIS deliver mail message to a mail application or Web page delivered to the client Web browser, IIS also sends the MIME type of data transfer. If there are additional or embedded files that are passed in a specific format, IIS notifies the client application to embed or attach the MIME type of the file. The client application then knows how to process or display the data being received from IIS. File

IIS only with the extensions registered in the MIME type list to provide services, and also allows you to configure additional MIME types and change or remove MIME types.

IIS pre-configured to identify the type of MIME global default settings. All MIME types that you create in IIS recognize these MIME types. MIME types can also be defined at the site and directory level, independent of other or globally defined types. When viewing a MIME type at the site or directory level, only the types that correspond to this level are displayed, not all types that are inherited from the previous level. If the MIME type is modified at a lower level and the same MIME type is applied at the global level, the MIME type at the global level overrides the MIME type modified at the lower level.

If the client requests cited the extension of the file that extension is not defined in the MIME types, IIS returns a 404.3 error. By adding a wildcard (*) MIME type, you can also configure IIS to serve all files, ignoring file extensions.
