A multipurpose internet mail extension, or MIME type, is an internet standard that describes the contents of internet files based on their natures and formats. This cataloging helps the browser open the file with the appropriate extension or plugin. Although the term includes the word “mail,” it is used for web pages, too.

MIME types contain two parts: a type and a sub-type.

Octet-stream does not refer to a specific type of file -- it could be anything from a. This associates the extension with the selected application for future use.

1. The type describes the categorization of MIME types that are linked to each other.
2. In contrast, a subtype is unique to a specific file type that is part of the type.

Here is the MIME type for HTML:

Distinguishing Among MIME Types

Following is a list of most MIME types, with their file extensions and the applications that use them. Many computers use file extensions to help identify file types. So, if you have a file with an odd extension on your website, you can look up the MIME type in this list.

Some types are prefixed with X, and some are prefixed with VND. These prefixes, respectively, refer to sub-types not listed with the Internet Assigned Numbers Authority or values specific to a vendor.

Overview

The <mimeMap> element of the <staticContent> element adds a unique MIME type to the collection of static content types. Each <mimeMap> entry must consist of two parts:

• A unique file name extension that is specified by the fileExtension attribute, for example, '.txt', '.png', etc.
• A MIME type for the file name extension that is specified by the mimeType attribute, for example, 'text/plain', 'image/jpg', etc.

Note

IIS 7 will not return file types that are not added to the <staticContent> element or that have mappings in the <handlers> element by default. This behavior prevents unauthorized access to files that do not have mappings in the IIS 7 configuration settings.

Compatibility

Setup

The <mimeMap> element of the <staticContent> element is included in the default installation of IIS 7.
