问题是：为什么自定义错误处理不适用于不存在的路径/目录？
更新了固定代码（感谢大家输入）：
*更新了web.config和global.asax的代码*
<httpErrors errorMode=\"Custom\">
<remove statusCode=\"500\" subStatusCode=\"-1\" />
<remove statusCode=\"404\" subStatusCode=\"-1\" />
<error statusCode=\"404\" subStatusCode=\"-1\" prefixLanguageFilePath=\"\" path=\"/*****.aspx\" responseMode=\"ExecuteURL\" />
<error statusCode=\"500\" subStatusCode=\"-1\" prefixLanguageFilePath=\"\" path=\"/*****.aspx\" responseMode=\"ExecuteURL\"/>
</httpErrors>
added this to the global.asax to stop IIS from handling my 500 errors
after @Kev\'s suggestions IIS handled my 500\'s these lines fixed that
HttpApplication myApplication = new HttpApplication();
myApplication.Response.TrySkipIisCustomErrors = true;
web.config

解决方法
从此评论到失望先生：
谢谢，我正在现场使用IIS 7和IIS 7.5。找到材料时让我知道。
如果您的应用程序在配置为以经典管道模式运行的应用程序池中运行，则非ASP.NET的内容将不会到达ASP.NET运行时。即不存在的文件夹。这些将由IIS直接处理。
您有两种选择：
将应用程序池设置为集成管道模式。如果IIS的错误处理“吞噬”了您的ASP.NET 404和来自ASP.NET的500状态代码，则可能还需要配置以下设置：
<configuration>
<system.webServer>
<httpErrors existingResponse=\"PassThrough\" />
</system.webServer>
</configuration>
<system.webServer>
<httpErrors>
<remove statusCode=\"404\" subStatusCode=\"-1\" />
<error statusCode=\"404\" prefixLanguageFilePath=\"\"
path=\"/404.aspx\" responseMode=\"ExecuteURL\" />
</httpErrors>
</system.webServer>
404
200
<error statusCode=\"404\" prefixLanguageFilePath=\"\"
path=\"404.html\" responseMode=\"File\" />
404
