是否可以将“ MVC 5路由”用作web.config的system.webServer httpErrors部分中错误元素中的路径？

Question

Can a "MVC 5 route" be used as a path in an error element in system.webServer httpErrors section in web.config?

<configuration>
...other config stuff...
<system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404"/>
      <error statusCode="404" path="/Error/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
  </system.webServer>
</configuration>

Answer 1

Yes, you can do that. With responseMode="ExecuteURL" IIS internally "redirects" (sends a request for the given URL) and writes the result to the response.

You might also want to set the existingResponse attribute in httpErrors to Replace .

Be aware that:

For architectural reasons, IIS 7.0 can only execute the URL if it is located in the same Application Pool. Use the redirect feature to execute a Custom Error in a different Application Pool.
