MIME类型就是设定某种扩展名的文件用一种应用程序来打开的方式类型，当该扩展名文件被访问的时候，浏览器会自动使用指定应用程序来打开。多用于指定一些客户端自定义的文件名，以及一些媒体文件打开方式。 MIME的英文全称是"Multipurpose Internet Mail Extensions" 多功能Internet 邮件扩充服务，它是一种多用途网际邮件扩充协议，在1992年最早应用于电子邮件系统，但后来也应用到浏览器。服务器会将它们发送的多媒体数据的类型告诉浏览器，而通知手段就是说明该多媒体数据的MIME类型，从而让浏览器知道接收到的信息哪些是MP3文件，哪些是Shockwave文件等等。服务器将MIME标志符放入传送的数据中来告诉浏览器使用哪种插件读取相关文件。 MIME能够支持非ASCII字符、二进制格式附件等多种格式的邮件消息。这个标准被定义在; RFC 2045，; RFC 2046，; RFC 2047，; RFC 2048，; RFC 2049等RFC中。 由RFC 822转变而来的RFC 2822，规定电子邮件标准并不允许在邮件消息中使用7位ASCII字符集以外的字符。正因如此，一些非英语字符消息和二进制文件，图像，声音等非文字消息都不能在电子邮件中传输。MIME规定了用于表示各种各样的数据类型的符号化方法。 浏览器接收到文件后，会进入插件系统进行查找，查找出哪种插件可以识别读取接收到的文件。如果浏览器不清楚调用哪种插件系统，它可能会告诉用户缺少某插件，或者直接选择某现有插件来试图读取接收到的文件，后者可能会导致系统的崩溃。传输的信息中缺少MIME标识可能导致的情况很难估计，因为某些计算机系统可能不会出现什么故障，但某些计算机可能就会因此而崩溃。
