    #3、default_type如果Web程序没设置，Nginx也没找到对应文件的扩展名的话，就使用默认的Type，这个在Nginx 里用 default_type定义: default_type application/octet-stream，这是应用程序文件类型的默认值。

    sendfile        on;
    #4、sendfile: 设置为on表示启动高效传输文件的模式。sendfile可以让Nginx在传输文件时直接在磁盘和tcp socket之间传输数据。如果这个参数不开启，会先在用户空间（Nginx进程空间）申请一个buffer，用read函数把数据从磁盘读到cache，再从cache读取到用户空间的buffer，再用write函数把数据从用户空间的buffer写入到内核的buffer，最后到tcp socket。开启这个参数后可以让数据不用经过用户buffer。
