求助，试用了这个模块合并后的请求，浏览器一直返回400错误，文件类型是一样的，都是js，具体设置如下：

nginx 的版本：
mactekiMacBook-Pro-3:~ mac$ nginx -V
nginx version: nginx/1.5.7
built by clang 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --http-proxy-temp-path=/var/nginx/proxy --http-fastcgi-temp-path=/var/nginx/fastcgi --http-client-body-temp-path=/var/nginx/client --add-module=nginx-http-concat

nginx.conf设置：
location /sea-modules/ {
concat on;
concat_max_files 20;
}
文件目录就是html-->index+sea-modules

浏览器报错提示：
Request URL:http://localhost/sea-modules/arale/??class/1.1.0/class.js,events/1.1.0/events.js
Request Method:GET
Status Code:400 Bad Request

紧急求助，还望各位大牛能帮我解答一下

Start by reproducing the GET request shown in the report with nginx 1.5.7 and the provided nginx.conf location block. Inspect the nginx-http-concat module behavior for this URL and configuration; the work is done when the source of the 400 response is identified and a verified configuration or compatibility resolution is documented.
