链接地址带&符号， 400 Bad Request，求助

[majin]

之前网站改版原来的直接停止解析了。不久前换到阿里 windows 虚机。

然后带&的链接全部返回 400，虽然 robots 禁止抓取后蜘蛛不再光顾了..
问：如何让带&等符号的不存在的页面 返回为 404 呢

公司站不方便留网址，贴一下 web.config，提前谢谢了。

网站改版应该把原地址 301 到新地址吧……

[majin]

@TimePPT 没有换域名

[majin]

@TimePPT 原站全是重复页面，网站结构也很差，十几年域名没权重的，以往权值直接丢弃了。现在除了这个 400 状态码别的正常。

[TimePPT]

@majin 这个跟域名没关系啊，就是个 URL 按照新旧对应关系处理成 301 永久性跳转就行。

[TimePPT]

@majin 哦哦这样啊，&后面这些就是 URL 参数，你后端处理 404 时候其实只用判断 baseurl 就行，甭管带不带参统一返回 404 就行。后端技术我不熟，就是恰巧做过改版跳转链接的产品活，具体实现你查查应该有
