MIMETYPE 与 Content_type的关系

MIME Type 与 Content-Type 的关系

当web服务器收到静态的资源文件请求时，依据请求文件的后缀名在服务器的MIME配置文件中找到对应的MIME Type，再根据MIME Type设置HTTP Response的Content-Type，然后浏览器根据Content-Type的值处理文件。

首先看看tomcat服务器中默认的web.xml中的描述：

<!-- ===================== Default MIME Type Mappings =================== -->

<!-- When serving static resources, Tomcat will automatically generate -->

<!-- a "Content-Type" header based on the resource's filename extension, -->

<!-- based on these mappings. Additional mappings can be added here (to -->

<!-- apply to all web applications), or in your own application's web.xml -->

<!-- deployment descriptor. -->

再看看apache服务器中mime.types的描述：

# This file controls what Internet media types are sent to the client for

# given file extension(s). Sending the correct media type to the client

# is important so they know how to handle the content of the file.

# Extra types can either be added here or by using an AddType directive

# in your config files. For more information about Internet media types,

# please read RFC 2045, 2046, 2047, 2048, and 2077. The Internet media type

# registry is at <http://www.iana.org/assignments/media-types/>.
