我在网站日志中看到许多这样子的代码，

H10008878 220.181.158.218 - - [22/Sep/2016:10:49:14 +0800] "GET ../../../../../windows/win.ini HTTP/1.1" 400 226 "http://www.joincircuit.com/news/6/../../../../../../../../windows/win.ini" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; .NET CLR 1.1.4322)"

这个是百度蜘蛛吗？可是据我所知，ini是配置文件，get配置文件做什么呢？这个IP 220.181.158.218 是北京的，日志中有很多这样子的代码，实在不明白这是在干吗，如果索取配置文件，是不是说明有人在窃取网站代码做配置，网站有被镜像的可能性？

可是这个IP究竟是啥呢？

额 再补充下，还有许多这样子的代码

H10008878 220.181.158.218 - - [22/Sep/2016:10:49:15 +0800] "GET /..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252fwindows/win.ini HTTP/1.1" 404 2267 "http://www.joincircuit.com/..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252f..%252fwindows/win.ini" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; .NET CLR 1.1.4322)"

乱七八糟，有点看不懂，这是在干啥？
