MIME 类型
MIME (Multipurpose Internet Mail Extensions) 是描述消息内容类型的因特网标准。
MIME 消息能包含文本、图像、音频、视频以及其他应用程序专用的数据。
官方的 MIME 信息是由 Internet Engineering Task Force (IETF) 在下面的文档中提供的：
- RFC-822 Standard for ARPA Internet text messages
- RFC-2045 MIME Part 1: Format of Internet Message Bodies
- RFC-2046 MIME Part 2: Media Types
- RFC-2047 MIME Part 3: Header Extensions for Non-ASCII Text
- RFC-2048 MIME Part 4: Registration Procedures
- RFC-2049 MIME Part 5: Conformance Criteria and Examples
不同的应用程序支持不同的 MIME 类型。
下面的参考手册是由 Microsoft Internet Information Server version 5 所支持的 MIME 类型列表。
