web - nginx禁止自动转换目录为index.html

Question

我有一个奇怪的用途.
我用aria2做了个下载机,用nginx做下载目录的索引,autoindex已开,然而,如果我用aria2不小心下载了某个网站的首页或者下载后保存为了index.html,当我去访问这个下载目录时,会直接打开index.html,我希望它永远不要自动做这个事情,哪怕有index.html也不要去打开它.我首先是把index去掉,发现根本无效,之前会自动解析index.html的地方仍然会解析.于是我尝试了index ;这样一个参数,发现nginx启动不起来会报错.
我现在希望做到只有访问根路径/时会自动选择index.html显示,而访问/down和/res下时会忽略掉index.html直接显示目录下的文件列表.
以下是我对应虚拟主机的设置:

# You may add here your
# server {
#       ...
# }
# statements for each of your virtual hosts to this file

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.

# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
