什么是 MIME TYPE？
一、首先，我们要了解浏览器是如何处理内容的。在浏览器中显示的内容有 HTML、有 XML、有 GIF、还有 Flash ……那么，浏览器是如何区分它们，决定什么内容用什么形式来显示呢？答案是 MIME Type，也就是该资源的媒体类型。
媒体类型通常是通过 HTTP 协议，由 Web 服务器告知浏览器的，更准确地说，是通过 Content-Type 来表示的，例如:
Content-Type: text/HTML
表示内容是 text/HTML 类型，也就是超文本文件。为什么是“text/HTML”而不是“HTML/text”或者别的什么？MIME Type 不是个人指定的，是经过 ietf 组织协商，以 RFC 的形式作为建议的标准发布在网上的，大多数的 Web 服务器和用户代理都会支持这个规范 (顺便说一句，Email 附件的类型也是通过 MIME Type 指定的)。
通常只有一些在互联网上获得广泛应用的格式才会获得一个 MIME Type，如果是某个客户端自己定义的格式，一般只能以 application/x- 开头。
XHTML 正是一个获得广泛应用的格式，因此，在 RFC 3236 中，说明了 XHTML 格式文件的 MIME Type 应该是 application/xHTML+XML。
当然，处理本地的文件，在没有人告诉浏览器某个文件的 MIME Type 的情况下，浏览器也会做一些默认的处理，这可能和你在操作系统中给文件配置的 MIME Type 有关。比如在 Windows 下，打开注册表的“HKEY_LOCAL_MACHINESOFTWAREClassesMIMEDatabaseContent Type”主键，你可以看到所有 MIME Type 的配置信息。
二、在把输出结果传送到浏览器上的时候，浏览器必须启动适当的应用程序来处理这个输出文档。这可以通过多种类型MIME（多功能网际邮件扩充协议）来完成。在HTTP中，MIME类型被定义在Content-Type header中。
例如，架设你要传送一个Microsoft Excel文件到客户端。那么这时的MIME类型就是“application/vnd.ms-excel”。在大多数实际情况中，这个文件然后将传送给Execl来处理（假设我们设定Execl为处理特殊MIME类型的应用程序）。在ASP中，设定MIME类型的方法是通过Response对象的ContentType属性。
多媒体文件格式MIME
最早的HTTP协议中，并没有附加的数据类型信息，所有传送的数据都被客户程序解释为超文本标记语言HTML 文档，而为了支持多媒体数据类型，HTTP协议中就使用了附加在文档之前的MIME数据类型信息来标识数据类型。
MIME意为多目Internet邮件扩展，它设计的最初目的是为了在发送电子邮件时附加多媒体数据，让邮件客户程序能根据其类型进行处理。然而当它被HTTP协议支持之后，它的意义就更为显著了。它使得HTTP传输的不仅是普通的文本，而变得丰富多彩。
每个MIME类型由两部分组成，前面是数据的大类别，例如声音audio、图象image等，后面定义具体的种类。
常见的MIME类型
超文本标记语言文本 .html,.html text/html
普通文本 .txt text/plain
RTF文本 .rtf application/rtf
GIF图形 .gif image/gif
JPEG图形 .ipeg,.jpg image/jpeg
au声音文件 .au audio/basic
MIDI音乐文件 mid,.midi audio/midi,audio/x-midi
RealAudio音乐文件 .ra, .ram audio/x-pn-realaudio
MPEG文件 .mpg,.mpeg video/mpeg
AVI文件 .avi video/x-msvideo
GZIP文件 .gz application/x-gzip
TAR文件 .tar application/x-tar
Internet中有一个专门组织IANA来确认标准的MIME类型，但Internet发展的太快，很多应用程序等不及IANA来确认他们使用的MIME类型为标准类型。因此他们使用在类别中以x-开头的方法标识这个类别还没有成为标准，例如：x-gzip，x-tar等。事实上这些类型运用的很广泛，已经成为了事实标准。只要客户机和服务器共同承认这个MIME类型，即使它是不标准的类型也没有关系，客户程序就能根据MIME类型，采用具体的处理手段来处理数据。而Web服务器和浏览器（包括操作系统）中，缺省都设置了标准的和常见的MIME类型，只有对于不常见的 MIME类型，才需要同时设置服务器和客户浏览器，以进行识别。
由于MIME类型与文档的后缀相关，因此服务器使用文档的后缀来区分不同文件的MIME类型，服务器中必须定义文档后缀和MIME类型之间的对应关系。而客户程序从服务器上接收数据的时候，它只是从服务器接受数据流，并不了解文档的名字，因此服务器必须使用附加信息来告诉客户程序数据的MIME类型。服务器在发送真正的数据之前，就要先发送标志数据的MIME类型的信息，这个信息使用Content-type关键字进行定义，例如对于HTML文档，服务器将首先发送以下两行MIME标识信息,这个标识并不是真正的数据文件的一部分。
Content-type: text/html
注意，第二行为一个空行，这是必须的，使用这个空行的目的是将MIME信息与真正的数据内容分隔开。
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。
