asp.net - 添加默认路径时，HttpError iis配置会引发异常

Question

我有此配置可以正常工作并正确重定向以下错误

<httpErrors errorMode="Custom" 
        existingResponse="Replace" 
        defaultResponseMode="ExecuteURL" >
  <remove statusCode="403" />
  <remove statusCode="404" />
  <remove statusCode="500" />
  <error statusCode="403" responseMode="ExecuteURL" path="/Error/AccessDenied" />
  <error statusCode="404" responseMode="ExecuteURL" path="/Error/PageNotFound" />
  <error statusCode="500" responseMode="ExecuteURL" path="/Error/ApplicationError" />
</httpErrors>

但是当我添加以下默认路径以尝试添加全部内容时

<httpErrors errorMode="Custom" 
        existingResponse="Replace" 
        defaultResponseMode="ExecuteURL" 
        defaultPath="/Error/ApplicationError">

服务器抛出一个web.config错误

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Module     CustomErrorModule

现在，这与 documentation on msdn直接矛盾

任何帮助将不胜感激!!

在错误节点中，使用defaultPath属性可防止使用path属性。因此，下面的配置将起作用(但对于在此定义的所有HTTP错误，当然会显示相同的错误页面):

<httpErrors errorMode="Custom" existingResponse="Replace"
  defaultResponseMode="ExecuteURL" defaultPath="/Error/ApplicationError">
  <remove statusCode="403" />
  <remove statusCode="404" />
  <remove statusCode="500" />
  <error statusCode="403" responseMode="ExecuteURL" />
  <error statusCode="404" responseMode="ExecuteURL" />
  <error statusCode="500" responseMode="ExecuteURL" />
</httpErrors>
